## Question 418:

Dear Stats Person,Here is my question. If a person were to guess a number from 1-10, the chance of guessing a 4 would be 0.1. If 5 people were asked to guess a number from 1-10, the chance of guessing a 4 would be 0.5. The chance of 2 people guessing a 4 would be (0.1)(01.)=(0.01), correct? Shouldn't the total number of people also be accounted for? That is what is the chance of 2 people guessing a 4 out of 8 people? or 2 people guessing a 4 out of 20 people guessing? What about the chance of 3 people guessing 4 out of 50 people guessing? Is there a formula for this?

Thank you.

Diane
