The numbers 1 to 50 are in a hat. If the probability of drawing an even number is 25/50, what is the probability of NOT drawing an even number? Express this probability as a fraction.

25/50

To find the probability of NOT drawing an even number, we need to subtract the probability of drawing an even number from 1 (since the sum of the probabilities of all possible outcomes is always 1).

The probability of drawing an even number is given as 25/50, which can be simplified to 1/2.

Therefore, the probability of NOT drawing an even number can be calculated as:

1 - 1/2 = 1/2.

So, the probability of not drawing an even number is 1/2.
