Question

A bag contains 8 black marbles 16 white marvels 14 red marbles 14 red marbles and 10 green marbles a marble is drawn at random what is the probablity the marble drawn will not be white

Answer 1

2/3 as you add 14 10 and 8 to get 32 and then add the 16 to get 48. This becomes 32/48 or 16/32. This can simplify to 2/3 however most do not simplify when it comes to probability so 32/48

Answer 2

i think it would be 2/3

first add up the number of marbles which aren't white and divide that by the total number of marbles.

8 + 14 + 10 = 32

32/48 = 2/3

then find the total number of marbles, divide the number of white marbles by the total, then do 1 minus the answer.

16/48 = number of white marbles

1 - 16/48 = 2/3

hope this helps
