Question

PLEASE HURRY
A bag contains balls with the numbers 1 through 7 on them. A ball was drawn 165 times. The one ball was drawn 10 times, the three ball was drawn 12 times, the five ball was drawn 7 times, and the seven ball was drawn 9 times. What is the experimental probability of drawing an odd number?

Answer 1

1, 3, 5 and 7 are all odd numbers.
How many times was 1 drawn in this experiment? 3? 5? 7?
Form the four corresponding probabililties (e. g., the prob. of drawing a 1, the prob. of drawing a 3, and so on). Then add them together.

Example: Prob. of drawing a 1 is 10/165. What are the probs. of drawing a 3, a 5, a 7?
