Question

A fair coin is tossed two times in succession. The set of equally likely outcomes in {HH,HT,TH, TT}. Find the probability of getting exactly zero tails.​

Answer 1

The probability is 0.25

Explanation:

From the given it is obtained that a fair coin is tosses two times in succession

The set of equally likely outcomes in {HH,HT,TH, TT}.

Which shows that there is one (H,H) chance in which there is no tail

So there is one chance of not getting tail out of four possible outcomes.

Probability (P) = ¼

P = 0.25

Answer 2

1/4

Explanation:

The answer is 1/4 because their is a total number of 4 outcomes (denominator) and there in only 1 chance (numerator) that you will not get tails.
