Question

please answer

what is the probability of heads in a fair coin ?

Answer 1

Solution:

Sampe space for fair coin is [ H, T ].

The Probability of an outcome of heads on the toss of a fair coin is 1/2 or 0.5.

We know that the probability of an event can be expressed as percentage. In this case, it is 50%.

Similarly, sample space for pair of fair coin is [ HH, HT, TH, TT ].

The probability of getting two heads on two fair coin tosses is 0.5 x 0.5 or 0.25. (by product rule).

Therefore, by using product rule, we can find out the probability of heads in a fair coin.
