Question

Student A has a probability of 0.9 of solving a problem while student B has a probability of 0.6 of solving the problem. What is the probability that both of them will solve the problem?0.240.720.540.65

Answer 1

We have two students with different probabilities of solving a problem, we are asked to find the probability that student A solves it and also student B solves it.

For this we use the multiplicative rule, this rule concerns the probability of two events happening at the same time. happening at the same time. If the events are independent, then, the probability of the two events happening both events is equal to the product of their respective probabilities. probabilities.

So we multiply the probability of both events:

`0.9\cdot0.6=0.54`

In conclusion, the answer is 0.54
