The probability of pulling a red marble out of a jar of marbles is 7/20 and this can be determined by using the given data.

Given :

A jar of marbles have 10 green  marbles, 7 red marbles and 3 blue marbles.

The following steps can be used in order to determine the probability of pulling a red marble out of a jar of marbles:

Step 1 - The total number of marbles in the jar is:

$\rm Total\; Marbles = 10+7+3$

$\rm Total\; Marbles = 20$

Step 2 - The total number of red marbles in the jar is 7.

Step 3 - So, the probability of pulling a red marble out of a jar of marbles is:
