Ajar contains 30 red marbles 50 blue marbles and 20 white marbles if you select one marble from the jar at random what is the theoretical probability of getting a red marble

3/10

Step-by-step explanation:

P(red) = red marbles / total marbles

We have 30 red marbles

total marbles = (20 white+ 50 blue+ 30 red) = 100 marbles

P(red) = 30/100 = 3/10

0.30 or 30%.

Step-by-step explanation:

This = number of re marbles / total number of marbles

= 30 / (30+50+20)

= 30 / 100

= 0.30.
