The probability of randomly selecting a yellow marble out of the bag is $\frac{1}{5}$

Step-by-step explanation:

A bag contains:

We need to find the probability of randomly selecting a yellow marble out of the bag

Probability is the ratio of number of favorable outcomes to the total number of possible outcomes P(A) = $\frac{n(A)}{n(outcoms)}$

∵ A bag contains 7 red marbles, 5 yellow marbles, 6 blue

marbles, 4 green marbles, and 3 orange marbles

- Add all the color to find the number of total marbles

∴ n(all) = 7 + 5 + 6 + 4 + 3 = 25

∵ There are 5 yellow marbles

∵ P(yellow) = $\frac{n(yellow)}{n(all)}$

∴ P(yellow) = $\frac{5}{25}$

- Divide up and down by 5 to simplify the fraction

∴ P(yellow) = $\frac{1}{5}$

The probability of randomly selecting a yellow marble out of the bag is $\frac{1}{5}$
