Question

A bag contains 2 red marbles, 3 green marbles, and 2 black marbles what is the probability of NOT drawing out a black marble

Answer 1

5/7 percent chance of not drawing a black marble ~~

Answer 2

Answer:

P (not black ) = 5/7

Step-by-step explanation:

We need to know the total number of marbles

2 red + 3 green + 2 black = 7 marbles

P (not black ) = Not black/ total

                      = ((2 red+ 3 green)/ total

                     = 5/7
