Question

Kerry has a bag containing white and yellow marbles. Kerry randomly selects one marble, records the result, and returns the marble to the bag. The results of the first 65 selections are shown below:

* A yellow marble was selected 41 times.

* A white marble was selected 24 times.

Based on these results, what is the probability that the next marble Kerry selects, rounded to the nearest percent, will be yellow?

Answer 1

63%

Explanation:

41/65 = 0.6307

You get the 65 as the denominator by adding 41 + 24 which equals = 65.

Moving On: 0.6307 x 100 = 63.07 or instead of multiplying by 100, you could just move the decimal point 2 places to the right.

Since we got 63.07, you round and your answer woudld be 63%

You're welcome and have a nice day !!!

:D

Answer 2

The probability that next selection is yellow marble = 63% .

Explanation:

Given the selection of yellow marbles = 41 times.

The selection of white marble = 24 times.

Total number of selections made = 65

Now calculate the probability that the next selection will be the yellow marble. Therefore, the probability of getting yellow marble can be determined by dividing the yellow selection by total number of selections.

`\text{P(yellow)} = \frac{ \text{The selection of yellow marbles} }{ \text{ Total number of slections }} \\\text{P(yellow)} = (41)/(65) = 0.63 \ or \ 63 \ percent`
