Chapter 7: Q. 5 (page 462)

Suppose we roll a fair die four times. The probability that a $6$ occurs on exactly one of the rolls is
(a) $4 {(\frac{1}{6})}^{3} {(\frac{5}{6})}^{1}$
(b) $4 {(\frac{1}{6})}^{1} {(\frac{5}{6})}^{3}$
(c) $6 {(\frac{1}{6})}^{1} {(\frac{5}{6})}^{3}$
(d) ${(\frac{1}{6})}^{3} {(\frac{5}{6})}^{1}$
(e) ${(\frac{1}{6})}^{1} {(\frac{5}{6})}^{3}$

Short Answer

Expert verified

The probability that a $6$ occurs on exactly one of the rolls is option (c) $4 {(\frac{1}{6})}^{1} {(\frac{5}{6})}^{3}$ .

Step by step solution

01

Given information

We roll a fair die four times.

Find the probability that a $6$ occurs on exactly one of the rolls.

02

Explanation

The probability of $6$ is $1 / 6$ because all die rolls are independent

Then it follows the sampling distribution $(4, 1 / 6)$

The probability formula is because of the binomial probability density.

$X ~ binomial (4, 1 / 6)$

$P (X = 1) = (\begin{array}{l} 4 \\ 1 \end{array}) {(\frac{1}{6})}^{1} {(\frac{5}{6})}^{3} = 4 {(\frac{1}{6})}^{1} {(\frac{5}{6})}^{3}$

The factorial component is

$(\begin{array}{l} 4 \\ 1 \end{array}) = \frac{4!}{1! * (4 - 1)!} = 4$

So the answer is (c).
