Question

The probability that a student will solve problem A is 0.6 and that he will not solve problem B is 0.5. If the probability that the student solves at least one problem is 0.8. What is the probability that he will solve both the problems?

Answer 1

Answer:

0.3

Step-by-step explanation:

P(Can solve A) = 0.6

P(Can solve B) = 0.5

P(Can solve at least A or B ) = 0.8

Find the probability that a student can solve both:

P(Solve both) = 0.6 + 0.5 - 0.8 = 0.3

Answer: The probability is 0.3
