Question 244908: What is the probability that an integer between 1 and 50 inclusive is divisible by 3 or 4? Do this problem without enumerating all the numbers. Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! 3*16=48 so there are 16 numbers divisible by 3 less than 50.
4*12=48 so there are 12 numbers divisible by 4 less than 50.
The numbers 12, 24, 36, and 48 are counted twice since they're divisible by both 3 and 4 so take out one instance for each number.
N=16+12-4=24
P=24/50=12/25
