Question

An experiment is conducted with a bag of marbles containing 5 white and 2 blue marbles. The results of a marble being drawn twice and replaced 100 times are shown in the table.

Outcome Frequency
White, White 27
White, Blue 22
Blue, Blue 18
Blue, White 33

Find P(1 blue).
33 over 100
50 over 100
55 over 100
73 over 100

Answer 1

The probability P(1 blue) is: 55/100. Thus, option C is correct.

What is the probability?

Probability is a mathematical concept that describes the likelihood of an event occurring. It is a value between 0 and 1, where 0 means an event is impossible to occur and 1 means an event is certain to occur.

The probability of drawing one white and one blue marble can be found by adding the frequency of two possible outcomes: White, Blue and Blue, White. The frequency of these two outcomes is 22 + 33 = 55.

Hence, the probability of drawing one white and one blue marble is 55/100= 0.55, which is the answer to this question.

Therefore, the answer is: C. 55/100.
