Answer:

a. 0.308 = 30.8% probability that a red ball is drawn.

b. 0.816 = 81.6% probability that the ball drawn is not white.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

308 + 184 + 508 = 1000 balls

a.A red ball is drawn

308 balls are red. So

308/1000 = 0.308

0.308 = 30.8% probability that a red ball is drawn.

b.the ball drawn is not white.

1000 - 184 = 816 are not white.

816/1000 = 0.816

0.816 = 81.6% probability that the ball drawn is not white.
