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%

The  experimental probability of an odd number other than 9 being generated is 38%.

Experimental probability

Using this formula

Probability = Number of odd numbers other than nine / Total number of numbers

Let plug in the formula

Probability=(72-15)/150

Probability= 57/150

Probability= 0.38×100

Probability=38%

Therefore the correct option is A.
