Question

Leon has a bag of 4 red balls, 3 green balls and 6 yellow balls. He takes a ball out and replaces it 50 times. Out of those 50 trials he pulls out a green ball 12 times. What is the experimental probability of getting a green ball on his next trial?
A) 3:50


B) 6:25


C) 2:25


D) 6:50

Answer 1

Answer: B) 6:25

Step-by-step explanation:

Given: the number of times green balls were pulled = 12

The total number of times he took the balls and replaced = 50

Now, the experimental probability of getting a green ball on his next trial is given by :-

$\text{P{G}}=\frac{12}{50}=\frac{6}{25}$

Hence, the experimental probability of getting a green ball on his next trial $=\frac{6}{25}$ or 6:25

Answer 2

B. ratio = 12:50
12/2=6 and 50/2=25
it cannot be broken down more after this is done.

so your answer is b
