navik [9.2K]

Answer:

\boxed {\boxed {\sf B. \ \frac{8}{13} }}

Step-by-step explanation:

Probability is found by dividing the number of favorable outcomes by the total number of outcomes.

P= \frac{favorable \ outcomes}{total \ outcomes}

For this problem, the favorable outcome is selecting a blue or green marble. There are 8 outcomes for this because there are 6 outcomes for blue and 2 fr green.

The total outcomes are all the marbles. Each marble could be an outcome, so there are 13 outcomes (1 for each marble).

P(blue \ or \ green) = \frac{8}{13}

This fraction cannot be reduced, so the probability of selecting a blue or green marble is <u>8/13.</u>
