Chapter 6.3, Problem 101E

To determine

To calculate; the type of distribution.

Answer to Problem 101E

The right option is (b)

Explanation of Solution

Given; Assumed probability is $1$ out of $4$

Randomly 3 are chosen

Explanation;

  $P(win)=\frac{\text{no: of favorable outcomes}}{\text{no: of possible outcomes}}=\frac{1}{4}$

  $n=3(\text{Sample Size})$

Therefore, the distribution can be said to be binomial distribution where

  $\begin{array}{l}n=3\\ p=\frac{1}{4}\end{array}$

The distribution cannot be geometric because the sample size is given.
