Step-by-step explanation:

There are 10 marbles in a bag. 3 of them are red. What is the probability of picking a red marble at random from this bag?

The number of favorable outcomes (picking a red marble) is 3.

The total number of outcomes (total marbles) is 10.

the probability is:

Probability =3/10

Therefore, the probability of picking a red marble at random from this bag is 3/10 or 0.3
