Question

A random number generator is used to create a list of 150 single-digit numbers. Of those 150 numbers, 72 are odd and 78 are even. The number 9 was generated 15 times.

To the nearest whole percent, what is the experimental probability of an odd number other than 9 being generated?

Answer 1

Answer: A. 38%

Step-by-step explanation: If you want to know how to get this answer, just think: you have 15p single-digit numbers, and 72 odd. But it's asking for all the odd numbers except 9. 9 is generated 15 times. So, just do 72 (odd numbers) - 15 (generated 9's) = 67.

Then, do 67/150 converted to a %, which is 38%.

Hope this helped.

Have a nice day. :)

Answer 2

38%

Explanation:

Option: 38%.

Total number of numbers: 150

Number of odd numbers: 72

Number of nines: 15

Number of odd numbers other than nine: 72 - 15 = 57

Probability = [number of odd numbers other than nine] / [total number of numbers] = 57/150 = 0.38

0.38 = 38%
