.

The space of events is the set of all pairs of the form (a,L), where "a" is an integer number from 1 to 6 and "L" is a letter H or T.


The number "a" represents the outcome of thrown the die, while the letter L represents the outcome of tossing coin.


So, the space of events has 6*2 = 12 elements with the probability of  1%2F12  each.


Thus, in case (a)  the probability is  P = 1%2F12.


In case (b), the probability is 0 (zero), since the outcome "7" is impossible.


In case (c), the answer is  %281%2F2%29%2A%283%2F6%29 = %281%2F2%29%2A%281%2F2%29 = 1%2F4.

Solved.
