if the bowl contains 5 red marbles 7 blue marbles and 8 white marbles what is the probability you will draw a red marble when you pick one out?

5/20
15/20***
7/20
2/5

I’m stupid 2/5

Cause it’s “when you pick one out “ from the red ones and so theses only 5 red ones and you pick on marble

And so I think it’s 2/5

To find the probability of drawing a red marble, we need to calculate the ratio of the number of red marbles to the total number of marbles in the bowl.

In this case, the bowl contains a total of 5 red marbles, 7 blue marbles, and 8 white marbles. So the total number of marbles is 5 + 7 + 8 = 20.

The probability of drawing a red marble can be calculated as the number of red marbles divided by the total number of marbles:

P(red marble) = Number of red marbles / Total number of marbles

P(red marble) = 5 / 20

Simplifying this fraction, we get:

P(red marble) = 1/4

Therefore, the probability of drawing a red marble when picking one out is 1/4 or 0.25.

How did you get that answer?

No.

5 red marbles out of a total of 20.

Your wild guess is dead wrong!
