Question

if two coins are tossed similarly then find the probability of getting a) at least one head b) at least one tail​

Answer 1

The possible outcomes when two coins are tossed together are {HH,TT,HT,TH}. Therefore, the number of possible outcomes when two coins are tossed is 4.

Now, the possible outcomes of getting at least one tail are {TT,HT,TH}, which means the number of favourable outcome is 3.

Therefore, probability P of getting at least one tail is:

P= 4/3

Hence, the probability of getting at least one tail is

4/3
