Question

color of the ball red white black frquency 308 184 508 find the experimental probabilities of the following events happening a.A red ball is drawn b.the ball drawn is not white.​

Answer 1

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.
