Question

A pair of coins is tossed. What is the probability of no tails? 0 1/2 1/4

Answer 1

Answer:

Correct Answer is C 1/4

Step-by-step explanation:

Let E5 = event of getting no tail. Then,

E5 = {HH} and, therefore, n(E5) = 1.

Therefore, P(getting no tail) = P(E5) = n(E5)/n(S) = ¼

Answer 2

0 cannot be the answer. It makes no sense because you can get a probability of getting tails when flipping a coin.

The answer would be 1/2. You have '2' choices (heads or tails) and 1 out of those 2 times would you possibly get tails.
