Certain numbers of children were playing a game of football. There was a trial taking place on the field. In this trial the probability that a goal is scored is 2/5. The probability that a gril hits a goal is 7/10 whereas the probability than a boy hits a goal is 1/5. What will be the probability that not only a goal is hit but it is also hit by a boy?

We know that, the probability that two events will take place simultaneously is denoted by the product of the individual occurences of each of the different events. So The probability that a goal is scored and it is also scored by a boy = 25×15 = 225
