at least one head means minimum no of head is one and maximum three .
i)) outcome in which at least one head is 7 .
probability = 7/8
ii)) at most two head means maximum two head and minimum one .
outcome in which at least two head is 6 .
probability = 6/8 = 2/3
iii)) outcome in which exactly two head = 3
probability = 3/8
iv)) outcome in which no head = 1
probability = 1/8
total outcome = 8
