The probability that a fisherman from Clearwater had a licence is 45/50, and that the one from Mountain View did not is 30/60.

Step-by-step explanation:

45 in Clearwater had licences, and 5 didn't. That's a total of 50. 30 in Mountain View did, and 30 didn't. That's 60.

45 + 5 = 50 45/50 or 9/10 had licences-Clearwater

30 + 30 = 60 30/60 or 1/2 didn't have licences-Mountain View
