BRAINLIEST AND 50 POINTS

Answer:

P ( blue ) =  1/4

P ( white ) =  5/12

P ( red ) = 1/3

P ( not red ) =  2/3

Step-by-step explanation:

To find the probability of a marble being chosen,  it is the number of that color over the total

We need to find the total number of marbles

4 red+ 5 white+3 blue = 12 marbles

P ( blue ) = 3 blue / 12 total = 3/12 = 1/4

P ( white ) = 5 white / 12 total = 5/12

P ( red ) = 4 red/ 12 total = 4/12 = 1/3


How man marbles are not red

total marbles - red marbles = 12-4 = 8

8 marbles are not red

P ( not red ) = 8 not red / 12 total = 8/12 = 2/3
