Question

Identify the following distribution as binomial, geometric or neither A quarter back completes 44% of his passes. We want to observe this quarterback during one game to see how many pass attempts he makes before completing one pass.

a) Binomial
b) Geometric
c) Neither

Answer 1

b) Geometric

Explanation:

given that the a quarter back completes 44% of his passes. We want to observe this quarterback during one game to see how many pass attempts he makes before completing one pass.

This is a geometric distribution because we are considering the random variable as number of attempts he makes before passing first time.

It is not binomial since number of trials is not fixed

It is a geometric distirbution.

Option b is right

Recall that a geometric distribution is the number of trials before you get first success.
