Question

probability of getting no head​

Answer 1

Answer:

So the probability of getting no head is ¼. Now if we consider the total chance of getting at least one head in tossing the coin is 3 i.e, {HH, HT, TH} out of the 4 sample points. So the total probability of getting at least one head is ¾. ... So the probability of getting no head is = (1-¾)=¼.

Answer 2

total outcome=2

favourable outcome=1

probability=1/2
