There are 5 radar stations and the probability of a single radar station detecting an enemy plane is 0.65. What is the probability of 3 stations detecting an enemy plane?

probability of a single radar station detecting an enemy plane is 0.65..

probability of 3 stations detecting an enemy plane = ( 5 C 3) ( 0.65) ^3 * ( 0.35)^2 = 0.336415625....
