Question

A bowl has only red, green, and purple grapes. The probability of picking a red grape out of the bowl, eating it, and then picking a green grape out of the bowl is 1/8 The probability of picking just a red grape is 1/4 . What is the probability of picking a green grape?

Answer 1

The probability of picking a green grape is 1/2.

What is probability?

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.

Since the probability of picking a red grape out of the bowl, eating it, and then picking a green grape out of the bowl is 1/8 and probability of picking just a red grape is 1/4 .

The probability of green grape will be the division. This will be:

= P(R and G) / P(R)

= 1/8 ÷ 1/4

= 1/8 × 4/1

= 1/2

The probability is 1/2.
