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.
