What is the probability that three tails do not come up on a throw of three Dimes?
I dont know how to set up and answer this one, any help would be appreciated
The probability that all three coins come up tails is 0.5*0.5*0.5 = 0.125
Call this P(x)
P(not x) can be calculated by 1 – P(x)
P(not x) is the probability that they don’t all come up tails
So in this case 1 – 0.125
Your answer is 0.875
