What is the probability of picking an odd number and then picking a 9?

Write your answer as a percentage.

Answer 1

[AI-generated answer — Bot GPT 3.5]

The probability of picking an odd number first is 2/4 (since there are 2 odd numbers out of the 4 choices).

Then, the probability of picking a 9 is 1/4.

Therefore, the probability of picking an odd number and then picking a 9 is:

(2/4) * (1/4) = 2/16 = 1/8 = 0.125

Converting to a percentage: 0.125 * 100% = 12.5%

So, the probability of picking an odd number and then picking a 9 is 12.5%.
