Answer:

64.60% probability that all are able to solve the problem

Step-by-step explanation:

We have these following probabilities:

A 95% probability that the first student solves the problem.

An 85% probability that the second student solves the problem.

An 80% probability that the third student solves the problem.

What is the probability that all are able to solve the problem

The probabilities are independent, so we can just multiply them

0.95*0.85*0.8 = 0.646

64.60% probability that all are able to solve the problem
