Question

A fair coin is tossed three times. What is the probability of getting at most two heads?

Answer 1

sorry i did wrong since there is given atmost hence there would be 7/8

Answer 2

@jollysailorbold there would be 7 favorable outcomes for at most 2 heads , it would not be 2 or 3 heads , i think that it would be 1 , 0 or 2 heads since it is given AT MOST NOT AT LEAST . hence i think answer is 7/8

Answer 3

A coin is tossed 3 times probability of at least 2 heads?
in the link u gave there is AT LEAST NOT AT MOST , hence the correct answer is 7/8

Answer 4

good job kushashwa.

Only one of the 8 possible outcomes has more than 2 heads.
The probability of getting at most 2 heads is 7/8.
