Question

the accompanying table describes the random variable x, the numbers of adults in groups of five who reported sleepwalking. complete parts (a) through (d) below. click the icon to view the table. a. find the probability of getting exactly 4 sleepwalkers among 5 adults (type an integer or a decimal. do not round.) probability distribution for x x p(x) 0 0.157 1 0.437 2 0.243 3 0.126 4 0.034 5 0.003

Explanation:

Step1: Identify from probability table

The probability of a value of the random - variable \(x\) is given in the table. We want the probability when \(x = 4\).

Step2: Read the probability

From the table, when \(x = 4\), \(P(x)=0.034\).

Answer:

0.034
