Question

A different bag contains several marbles. Each marble is red or white or blue. The probability of choosing a red marble is 1/3, and the probability of choosing a white marble is 1/6.

What is the probability of choosing a blue marble? Explain.

Answer 1

The probability of pulling a blue is 1/2

Answer 2

The probability of choosing a blue marble is 3/6 or 1/2 because 1/3 +1/6 equals 3/6. Meaning that only 3/6 is left over for blue's probability.
