a survey from a research firm found that 30% of teenage consumers receive their spending money from parttime job.if five teenagers are selected at random,find the probability that only three of them will have parttime jobs.

The easiest way to do this problem is to use a binomial probability table. Your values to look up in the table would be the following:
n = 5, p = .3, and x = 3
I hope this will help.
