50/50
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.
It is 0.75
the probability of getting one head and one tail on three flips of a coin is 1/9
When two fair coins are tossed, you have the following possible outcomes: HH, HT, TH, TT. So, at most implies that you get either i) zero heads or ii) one head. From the possible outcomes we see that 3 times we satisify the outcome. Thus, probability of at most one head is 3/4.
3/8 * * * * * That is the probability of getting EXACTLY 1H. The prob of getting one (or more) head is 7/8
50/50
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
1/2 or 50% (1/8 prob of 0H + 3/8 prob of 1H)
Assuming that it is a fair coin, the probability is 0.9990
the probability of getting one head and one tail on three flips of a coin is 1/9
