a. Explanation Here, the coin is tossed 3 times and the sequence of heads and tails is noted. Let h be heads and t be tails. When three coins are tossed randomly, the total number of possible outcome is 8 and the sample space is { h h h , h h t , h t t , h t h , t t t , t t h , t h h , t h t } . From the sample space, it can be observed that the event of getting “at least one head” is { h h h , h h t , h t t , h t h , t t h , t h h , t h t } and the event of getting “two or more heads” is { h h h , h h t , h t h , t h h } . The event of getting “two or more heads and at least one head” is { h h h , h h t , h t h , t h h } b. To determine Find the probability of two or more heads given that there was at least one tail.
