A coin is tossed 3 times and the outcome of heads or tails recorded for each toss. This is repeated until there have been 3 coin tosses 25 times. This list shows the results.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The total outcome set

T = {HTT, HHH, HTH, THT, THH, THT, THH, THT, HHT, TTH, HHH, TTT, HHT, THH, HTT, HHH, THT, HTT, HHT, HTH, THH, HTT, THH, TTH, HTT}

n(T) = 25

Total favourable outcome n(E) = 10

The probability = 10/25 = 0.4

= 0.4×100 = 40%

Thus, the experimental probability of getting exactly 2 heads out of 3 coin tosses is 40% option second is correct.
