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.
