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