Answer:
The Answer is 60%
Since the question asked for the probability of odd or prime number, we'll have 9 numbers that'll fit the condition. Odd numbers are 1,3,5,7,9,11,13,15
and prime numbers are 1,2,3,5,7,11,13. If we combine the numbers we'll get 1,2,3,5,7,9,11,13,15. Count the numbers and you'll get 9. Divide 9 by 15 and you'll get 0.6 then multiply it by 100 to get the percentage or probability which is 60%.
