Three students

Three students independently try to solve the problem. The first student will solve a similar problem with a probability of 0.6, the second student will solve at a probability of 0.55, and the third will solve at a probability 0.04. The problem is resolved, What is the probability that the first student has solved it?

Correct result:

p =  0.4963

Solution:

p1=0.6+0.550.6 0.55=0.82 p2=p1+0.04p1 0.04=0.82+0.040.82 0.04=517625=0.8272  p=0.6 p2=0.6 0.8272=0.4963
