Question

A survey found the distribution of some families by size and is as follows

Find the probability of family with 2 people.


p(2)=?

Need help ASAP

Answer 1

There are
`87+50+61+31+16+3+2 = 250` total families, and 87 of those are families with 2 people in them. So, the probability of choosing a family with 2 people in it is 87/250, 34.8%, or 0.348.

The probability p(2) = 0.348.

Hope this helped!
