Question

A supplies box contains 3 red crayons, 2 green crayons, and 6 blue crayons. If we choose a crayon, then another crayon without putting the first one back in the supplies box, what is the probability that the first crayon will be red and the second will be blue? Are these events independent or dependent? *

Answer 1

Answer:

16.36%

dependent

Step-by-step explanation:

If we choose a crayon, then another crayon without putting the first one back in the supplies box, that means the event is dependent. The keyword to find whether some events dependent is " without putting back" because that means the first pick will reduce the number of crayons pool for the second pick.

There are 3 + 2 + 6 = 11 total crayons. There are 6 blue and 3 red crayons. The probability for picking blue then red crayon will be:

6/11 * 3/10 = 18/110= 0.163636 = 16.36%
