A coin is tossed 25 times and the data is recorded as follows :Head - 15 timesTail - 10 timesThe probability of not getting a head is:
Three coins are tossed 200 times and we get
three heads: 39 times; two heads: 58 times;
one head: 67 times; 0 head: 36 times.
When three coins are tossed at random, what is the probability of getting (i) 3 heads? (ii) 1 head? (iii) 0 head? (iv) 2 heads?

(a) 25
(b) 35
(c) 15
(d) 45
