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. Which probability is relevant for determining whether 6 is a significantly high number of girls in 8​ births: the result from part​ (a) or part​ (b)?

Answer 1

The accompanying table describes results from groups of 8 births from 8 different sets of parents. the probability that exactly 1 is good in 8 births is mathematically given as

P (exactly good in 8 births)= 0.024

What is the probability that exactly 1 is good in 8 births?

Considering the fact that these children were raised by diverse sets of parents. Tabulated below are the outcomes of pregnancies involving eight distinct parent combinations.

Meaning "from the x-probability distribution"

P (exactly I girl in s births)

Given a table or distribution of probabilities,

P(girl) = p(x=1) for any x.

In other words, the probability that a given subject is a female is 0.024.

P (exactly good in 8 births)= 0.024
