Question

There are 87 green balls and 41 red balls in a bag. If one is randomly selected, what is the probability that it will be a green ball? Write answer as a decimal to the nearest hundredth.

Answer 1

Number of green balls = 87

Number of red balls = 41

So total number of balls = 128

Probability formula = number of events / number of possible outcomes.

So, the probability that a ball randomly selected will be a green ball will be

`(87)/(87+41)`

equals 0.6796875 converting to nearest hundredth as 0.68
