A hat contains 37 marbles. Of them, 14 are red and 23 are green. If one marble is randomly selected out of this hat, what is the probability that this marble is red?

To find the probability of selecting a red marble, we need to know the total number of marbles in the hat and the number of red marbles.

In this case, the hat contains a total of 40 marbles, with 16 of them being red. So, the probability of selecting a red marble can be calculated as:

Probability of selecting a red marble = Number of red marbles / Total number of marbles

In this case, the number of red marbles is 16, and the total number of marbles is 40. Therefore, the probability of selecting a red marble can be calculated as:

Probability of selecting a red marble = 16 / 40

Simplifying the fraction, we get:

Probability of selecting a red marble = 2 / 5

So, the probability of randomly selecting a red marble from the hat is 2/5 or 40%.
