Three coin§ are tossed simultaneously 180 times and it is found that 3 tails appeared 34 times, 2 tails appeared 55 times, 1 tail appeared 72 times and no tail appeared 19 times. Find the probability of getting

(i)3 tails (ii) 2 tails (iii) ltail (iv) 0 tail.

Given, total number of trials =180

Number of times 3 tails appeared = 34

Number of times 2 tails appeared = 55

Number of times 1 tail appeared = 72

Number ot times 0 tail appeared =19
