Question

A coin is tossed three times and a Random variable X represents the total number of tails obtained. Then possible values of X are:

Answer 1

The possible values of X are: 0, 1, 2, 3 [ANSWER]

Explanation:

On the three tosses of a coin, we can get 0 tails (if all the tosses result in heads) or we can get 1 tail (if any 1 of the three tosses results in a tail and the remaining 2 result in heads) or we can get 2 tails (if any 2 of the three tosses result in tails and the remaining toss results in a head) or we can get 3 tails (if all the 3 tosses result in tails).

Thus, if X is the total number of heads in three tosses of a coin, then the possible values of X are 0, 1, 2 and 3.
