Step-by-step explanatio

a) Two cards are dealt off a well-shuffled deck. You win $1 if the two cards are

of different suits. Find the probability of your winning?

b) A coin is tossed 5 times. What is the probability that the first toss is a head

or exactly 2 out of the five tosses are heads?

c) In a shuffled 52-card deck, what is the probability that neither the top nor

the bottom card is a heart?

d) A bag contains 20 red marbles, 20 green marbles and 20 blue marbles. You

reach in and grab 15 marbles. What is the probability that they are all the

same colour?

Answers

Answer:

A.) 0.7647 b.) 13/ 16 C.) 0.9412 D.) 8.743 * 10^-10

Step-by-step explanation:

A)

Number of cards per suit = 13

Nunber of suits = 4

Probability = required outcome / Total possible outcomes

P(1) = probability of picking a card from a certain suit

P(1) = 13 / 52

Hence, probability that 2nd card will be from a suit different from the first :

Total possible outcomes = (52 - 1) = 51

Required outcomes = (13 * 3) = 39

= 39 / 51

= 0.7647

B.)

First toss being head :

Required outcome = H = 1

Total possible outcomes = T or H = 2

P(H) = 1/ 2

For 5 tosses

Total possible outcomes = 2^n = 2^5 = 32

Exactly 2 heads = 10

P(exactly 2 heads) = 10/32 = 5/16

1/2 + 5/16 = (8 + 5) / 16 = 13/16

c)

1 - P(both top and bottom are hearts)

Number of hearts = 13 ; number of cards = 52

P(both are hearts) = 13/52 * 12/51 = 0.05882

1 - 0.05882

= 0.94117

= 0.9412

d)

Either all marbles are red OR all marbles are green OR all marbles are blue

Total number of marbles = (20 + 20 + 20) = 60

Probability that all 15 marbles are of a certain color :

(20/60 * 19/59 * 18/58 * 17/57 * 16/56 * 15/55 * 14/54 * 13/53 * 12/52 * 11/51 * 10/50 * 9/49 * 8/48 * 7/47 * 6/46)

(2.9146E−10) + (2.9146E−10) + (2.9146E−10)

= 8.7438E−10

= 8.743 * 10^-10

(504-300+800) x 100 / 3?

Answers

Answer:

  [1]    x - 6y = 3

  [2]    x + 2y = 5

Graphic Representation of the Equations :

   -6y + x = 3        2y + x = 5  

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -2y + 5

// Plug this in for variable  x  in equation [1]

  [1]    (-2y+5) - 6y = 3

  [1]     - 8y = -2

// Solve equation [1] for the variable  y

  [1]    8y = 2

  [1]    y = 1/4

// By now we know this much :

   x = -2y+5

   y = 1/4

// Use the y  value to solve for  x

   x = -2(1/4)+5 = 9/2

Solution :

{x,y} = {9/2,1/4}

A biology student wanted to determine if using fertilizer would promote plant growth. One hundred plants were randomly assigned to one of two groups: one that used the fertilizer, and one that did not use a fertilizer.

Which of the following is a benefit of having replication in the experiment?

B Having a large number of plants receiving the treatments will not allow for a good
comparison of the differences in plant growth between the two groups.

C Replication is not needed in this experiment. One plant receiving each type of treatment is enough to determine if the difference in plant growth is due to the fertilizer.
D Repeating the experiment will allow the student to compare the differences between the plants that received the fertilizer the first time and the plants that received the fertilizer the second time.
