That is the probability of getting EXACTLY 1H. The prob of getting one (or more) head is 7/8
is it 50% or 100% dang, i just confused myself. what if you toss 3 coins all at the same time... what's the probability of getting a head then, is it > 100% ? Doh!
Sample space for two coins tossed is: HH HT TH TT Therefore at most one head is HT TH TT or 3/4 or 0.75.
The probability is 3/4.
The probability is 50-50.
The probability is 1/4
It is 0.75
285 out of 500
obviously it is a 50-50 chance
Assuming that it is a fair coin, the probability is 0.9990
1/2 or 50% (1/8 prob of 0H + 3/8 prob of 1H)
the probability of getting one head and one tail on three flips of a coin is 1/9
