If you flip three coins simultaneously, what's the probability you'll get three heads for the first time on the fifth toss? a.125 b.1094 c.763 d.0733 e.5

In this question, you are flipping 3 coins simultaneously until you get all 3 heads, so we are looking at a binompdf, where x=5 (landing a success on the 5th trial), and p=0.5^3 (probability of success, meaning the probability of getting three heads). Plugging in to your calculator, binompdf(0.125,5)=0.0733

Yep this is right you
