If a ball is selected at random from an urn containing six red balls, six white balls, and eight blue balls, what is the probability that it will be a white ball
hint:
P(white)
=Number of white balls/total number of balls.
i got 0.3
I don't think MathMate mean to divide the number.
- I'm guessing he say to add the total amount up, and put it as the denominator while the amount of white ball is the numerator. Then you will have your probability of picking a white ball ( Simplify if needed).
Vanny, you are correct
6/20 = 0.3
or you can leave as 6/20 = 3/10
To find the probability of selecting a white ball, we need to know the total number of balls and the number of white balls in the urn.
In this case, the total number of balls in the urn is 6 (red) + 6 (white) + 8 (blue) = 20.
The number of white balls is 6.
So, the probability of selecting a white ball can be calculated as:
Probability of selecting a white ball = Number of white balls / Total number of balls
Probability of selecting a white ball = 6 / 20
Simplifying the fraction, we get:
Probability of selecting a white ball = 3 / 10
Therefore, the probability of selecting a white ball is 3/10, or 0.3, or 30%.
