Calvin makes 65% of the penalty kicks he takes. He is practicing penalty kicks with his friend Hobbes. He takes 10 shots. What is the probability that he makes exactly 7 of them?
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.
Calvin makes 65% of the penalty kicks he takes. He is practicing penalty kicks with his friend Hobbes. He takes 10 shots. What is the
From the provided information,
Sample size (n) = 10
Calvin makes 65% of the penalty kicks he takes that is p = 0.65
