Question

if you flip three fair coins, what is the probability that the first two flips will both be heads, and the third flip will be either heads or tails?

Answer 1

Well, any coin has a 1/2 chance of being heads or tails, so for the first two flips to be heads it would be 1/2*1/2=1/4. Now for the third coin flip, I’m not entirely sure what it’s asking but for any one side it will always be 1/2 no matter what previous flips came out to be.
Hope this helps!
