Question

one coin tossed two times find the probability of getting at least one tail​

Answer 1

There are 4 possible outcomes :- {HH, HT, TH, TT}. So there are three outcomes in which there is at least one tail. Therefore the probability should be 3/4 = 0.75. Probability= number of favorable outcomes / total number of possible outcomes.

Answer 2

Answer:

3/4

since HT TH TT HH will be the sample space.
