Every cereal box has a gift inside, but you cannot tell from the outside what the gift is. The store
manager assures you that 23 of the 44 boxes on the shelf have the secret decoder ring. The other
21 boxes on the shelf have a different gift inside. If you randomly select two boxes of cereal from
the shelf to purchase, what is the probability that BOTH of them have the secret decoder ring?
Answer:
529/1936
Explanation:
The chance that there would be a secret decoder ring in one is 23/44. The probability that it'll be in both boxes can be found by multiplying the chances in the case of the two boxes. For box A, the chance is 23/44. For box B, the chance is also 23/44. So when you multiply them, you have 529/1936.

The average number of times per night that Mrs. Plum's cats wake her up is 10/7.
We are interested in the number of times her cats wake her up in a given night.
Using a Poisson distribution, find the probability that Mrs. Plum's cats will wake
her up at least once in a given night. Write your answer rounded to the nearest
percent entered as a whole number.
The probability that Mrs. Plum's cats will wake her up at least once in a given night using the Poisson Distribution is: 0.7603
What is probability?Probability is a mathematical discipline that is concerned with numerical representations of how likely an event or statement is to occur. The likelihood of an event occurring is a number between 0 and 1, with 0 representing impossibility and 1 representing certainty.
A discrete probability distribution is a Poisson distribution. It expresses the likelihood of an event occurring a specific number of times (k) during a certain time or space period. The Poisson distribution has only one parameter, which is the mean number of occurrences, the λ (lambda).
Recall that the average number of times Mrs. Plum's cat wakes her up per night is given by λ = 10/7
Hence P (x ≥ 1) = 1- P (x < 1)
= 1 - P (X = 0)
= 1 - [e ⁻ ⁽¹⁰⁺⁷⁾ x (10/7)⁰]/0!

Using the normal distribution, it is found that the proportion of guests that will spend between 28 and 37 minutes in the house is:
0.6514.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the following rule:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above or below the mean, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X.In the context of this problem, the mean and the standard deviation are given as follows:
[tex]\mu = 35, \sigma = 4[/tex]
The proportion of guests that will spend between 28 and 37 minutes in the house is the p-value of Z when X = 37 subtracted by the p-value of Z when X = 28, hence:
X = 37:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (37 - 35)/4
Z = 0.5
Z = 0.5 has a p-value of 0.6915.
X = 28:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (28 - 35)/4
Z = -1.75
Z = -1.75 has a p-value of 0.0401.
Then the proportion is:
0.6915 - 0.0401 = 0.6514.

A foreman for an injection-molding firm admits that on 29% of his shifts, he forgets to shut off the injection machine on his line. This causes the machine to overheat, increasing the probability that a defective molding will be produced during the early morning run from 5% to 24%. If a molding is randomly selected from the early morning run of a random day, what is the probability that it is defective?
If a foreman for an injection-molding firm admits that on 29% of his shifts, he forgets to shut off the injection machine on his line in which a molding is randomly selected from the early morning run of a random day, the probability that it is defective is :10.51%.
Probability
First step is to analyze the event or the given scenario
Forgot to shut off the line (29% of the time) = leads to a 24% chance of defects in the morning
Did not forget to shut off the line (the other 71% of the time) = normal 5% chance of defects in the morning
(1-29% =71%)
Hence :
Now let determine the Probability that it is defective
Probability = [(.29)(.24)] + [(.71)(.05) ]
Probability = .0696 +.0355
Probability = .1051 × 100
Probability = 10.51%

Intramembranous ossification formed the flat bone of the cranium. Hence, option d is correct.
Bone ossification is process of formation of bones. It's of 2 types, Intramembranous and Endochondral. Thus, Intramembranous ossification directly converts mesenchymal tissue into the bones of skull, clavicle and a few cranial bones. Mesenchymal tissue is differentiated into osteoblasts and group into ossification centers. Osteoblasts secrete and entrap osteoid in it, transformed to osteocytes.
Further, in osteocytes trabecular bone and periosteum forms. Thus, cortical bone forms superficially to trabecular bones and blood vessels for red bone marrow. It is essential process for natural healing of bone fracture and rudimentary formation of bone head.
