Answer to Question #133439 in Statistics and Probability for Sougata Singh

Question

Arun can solve 70% of a mathematics book while Anjali can 60% from the same book. If a problem is given to both of them identify the probability to solve the problem

Answer 1

Given that,

Probability of Arun can solve the problem P(a) = 70% = 0.7

Probability of Anjali can solve the problem P(b) = 60% = 0.6

Probability to solve the problem is given by P = P(a) + P(b) - P(a)$\bigcap$ P(b)

P = 0.7 + 0.6 - 0.7*0.6

P = 0.88
