Question

What is the theoretical probability that any one color of marble is chosen?A: 2/6B. 1/5C. 1/6D. 6/6

Answer 1

Solution:

Given a glass jar with 6 different colored marbles in it.

If a color of marble is picked, the probability is 1/6

The theoretical probability that any one color of marble is chosen will be

$\begin{gathered} P=\frac{1}{6}+\frac{1}{6}+\frac{1}{6}+\frac{1}{6}+\frac{1}{6}+\frac{1}{6} \\ P=6(\frac{1}{6})=\frac{6}{6} \end{gathered}$

Hence, the answer is 6/6 (option D)
