Bree and Kendra love to go to the movies. When they go, there is a probability of 0.3 that Bree will buy popcorn. The probability that Kendra will buy popcorn is 0.35 if Bree buys popcorn and 0.65 if Bree does not. When Bree and Kendra go to the movies together, find the probability that both buy popcorn; 0.105 neither buys popcorn; 0.56 exactly one of them buys popcorn. 0.245 I have the top figured out, I cannot figure out the bottom. Carmelita accompanies Bree and Kendra to the movies sometimes. During these trips, the probability that Carmelita buys popcorn is 0.55 if both Bree and Kendra buy popcorn and 0.4 if exactly one of Bree and Kendra buys popcorn. When Bree, Kendra, and Carmelita go to the movies together, find the probability that 4. all three buy popcorn; 0.65? 5. Kendra and Carmelita buy popcorn, but Bree does not. How do I figure out #5? And is #4 correct? Thank you!
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
