Answer 1

P (not white) = 2/3

Explanation:

• No. of non-white marbles / Total marbles
• 8 + 14 + 10 / 8 + 16 + 14 + 10

• 2/3

Answer 2

2/3

Explanation:

There are 8 black marbles, 16 white marbles. 14 red marbles, and 10 green marbles.

8+ 16+14+10 = 48 marbles

8 black marbles + 14 red marbles+10 green marbles =32 are not white

P( not white) = not white marbles / total marbles

= 32/48

= 2/3
