Question

A random number generator is used to create a list of 200 single-digit numbers. Of those 200 numbers, 105 are even and ninety-five are odd. Seven was generated fifteen times.

What is the experimental probability of an odd number other than seven being generated?

40.0%
45.0%
47.5%
52.5%

Answer 1

There are 95 odd numbers total, of which 15 are sevens, so 95 − 15 = 80 odd numbers that are not seven.
Experimental probability = 80/200 = 0.40 = 40.0%.

Answer: 40.0%
