A number is selected at random from 1 to 50. The probability that it is divisible by 3 is 16/50. Using the complement, find how many numbers from 1 to 50 are NOT divisible by 3.

Question

Accepted Answer

34. Numbers divisible by 3 from 1-50: 3,6,...,48 = 16. Not divisible = 50 - 16 = 34 (also 1 - 16/50 = 34/50).

A number is selected at random from 1 to 50.
The probability that it is divisible by 3 is $\frac{16}{50}$ .
Using the complement, find how many numbers from 1 to 50 are NOT divisible by 3.
