Question

A bag contains 4 red balls and 6 green balls. You plan to select 3 balls at random. Determine the probability of selecting 3 green balls.

Answer 1

Total number of balls = 10
Red: 4/10chance of being selected
Green: 6/10 chance of being selected
Basically, there is a way higher chance of selecting 3 green balls and an even HIGHER chance of selecting 6!

Answer 2

Add the total number of balls and then see how many balls you are pulling and put it into a fraction and then simplify. So it would be 3/10
