Let S be the event that both cookies selected were the same flavor. Find P(S). (Enter your probability as a fraction.) Let T be the event that both cookies selected were different flavors. Find P(T) by two different methods: by using the complement rule and by using the branches of the tree. Your answers should be the same with both methods. (Enter your probability as a fraction.) Let U be the event that the second cookie selected is a butter cookie. Find P(U). (Enter your probability as a fraction.)
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.
A box of cookies contains 4 chocolate and 6 butter cookies. Miguel randomly selects a cookie and eats it. Then he randomly selects another cookie and eats it. (How many cookies did he take?)
- Let S be the
event that both cookies selected were the same flavor. Find P(S). (Enter yourprobability as a fraction.) - Let T be the event that both cookies selected were different flavors. Find P(T) by two different methods: by using the complement rule and by using the branches of the tree. Your answers should be the same with both methods. (Enter your probability as a fraction.)
- Let U be the event that the second cookie selected is a butter cookie. Find P(U). (Enter your probability as a fraction.)
