Question

the accompanying table describes results from groups of 8 births from 8 different sets of parents. the random variable x represents the number of girls among 8 children. complete parts (a) through (d) below. click the icon to view the table. a. find the probability of getting exactly 6 girls in 8 births. 0.119 (type an integer or a decimal. do not round.) b. find the probability of getting 6 or more girls in 8 births. (type an integer or a decimal. do not round.)

Explanation:

Step1: Identify the relevant probabilities

The probability of getting 6 girls is \(P(6) = 0.119\), the probability of getting 7 girls is \(P(7)=0.037\), and the probability of getting 8 girls is \(P(8) = 0.001\).

Step2: Calculate the probability of 6 or more girls

We use the formula \(P(x\geq6)=P(6)+P(7)+P(8)\).
Substitute the values: \(P(x\geq6)=0.119 + 0.037+0.001\).
