Erik is performing a marble experiment in math class. His teacher places an equal number of black, red, and white marbles in a bag. Then, Erik randomly takes out a marble, records the result, and puts the marble back in the bag. Each of the first four times Erik takes out a marble, he gets a black marble.

A. What is the theoretical probability of Erik picking a black marble next time? Based on Erik's results, what is the experimental probability of Erik picking a black marble next time?
B. Explain the difference between the two probabilities you found in part A.
C. What is the theoretical probability and likelihood of getting four black marbles in a row?

Answer:

Every one of us would have encountered multiple situations in life where we had to take a chance or risk. Depending on the situation, it can be predicted up to a certain extent if a particular event is going to take place or not. This chance of occurrence of a particular event is what we study in probability. In our everyday life, we are more accustomed to the word ‘chance’ as compared to the word ‘probability’. Since Mathematics is all about quantifying things, the theory of probability basically quantifies these chances of occurrence or non-occurrence of certain events. In this article, we are going to discuss what is probability and its two different types of approaches with examples.

Two dams, when opened, release water at different rates. The following functions represent the amounts of water the dams release over t minutes:

Dam A

f(t) = 5t – 7t – 1

Dam B

g(t) = 3t 2 + 4t + 9

Which function represents the difference in the amounts of water released, h(t) = f(t) – g(t)?

h(t) = 3t 2 – 5t + 11t + 10
h(t) = 2t 2 – 11t – 10
h(t) = 5t – 3t 2 – 3t + 8
h(t) = 5t – 3t 2 – 11t – 10

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Micaela sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.

196 visitors purchased no costume.
108 visitors purchased exactly one costume.
22 visitors purchased more than one costume.

Based on these results, express the probability that the next person will purchase more than one costume as a percent to the nearest whole number.
