a box contains 10 red balls and, 6 green balls and 4 yellow balls what is the probability of choose a random a green ball
20 total balls, 6 green, so
P(green) = 6/20
To find the probability of choosing a random green ball, we need to divide the number of favorable outcomes (the number of green balls) by the total number of possible outcomes (the total number of balls in the box).
In this case, the box contains a total of 10 red balls, 6 green balls, and 4 yellow balls. Therefore, the total number of possible outcomes is 10 + 6 + 4 = 20.
Since we are interested in selecting a green ball, the number of favorable outcomes is 6.
To calculate the probability, we divide the number of favorable outcomes (6) by the total number of possible outcomes (20):
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 6 / 20
Probability = 0.3 or 30%
So, the probability of choosing a random green ball is 0.3 or 30%.
