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? 38% 48% 52%

Explanation:

Step1: Find number of odd - non - 9 numbers

The total number of odd numbers is 72 and the number of 9s is 15. So the number of odd numbers other than 9 is $72 - 15=57$.

Step2: Calculate experimental probability

The experimental probability $P$ of an event is given by the formula $P=\frac{\text{number of favorable outcomes}}{\text{total number of outcomes}}$. Here, the total number of outcomes is 150 and the number of favorable outcomes (odd numbers other than 9) is 57. So $P=\frac{57}{150}= 0.38$.

Step3: Convert to percentage

To convert the decimal to a percentage, we multiply by 100. So $0.38\times100 = 38\%$.

Answer:

38%
