Question 1063399: The probability of that A can solve a problem in statistics is 4/5,B can solve it is 2/3 C can solve it is 3/7 if all of them try independently find the probability that the problem will be solved

Find the probability that they will all fail and subtract that from 1. There is only one way all 3 can fail, and there are many ways that 1 or more of the 3 can succeed.
That will be (1/5)(1/3)(4/7)=4/105
The probability it will be solved is 101/105.
