Question

A jar contains 6 red balls, 5 green balls, 3 white balls and 7 yellow balls. Two balls are chosen from the jar
with replacement. What is the probability that both balls chosen are white? Also what is the probability
choosing a red and then a green ball?​

Answer 1

Answer:

Step-by-step explanation:

We have a bag contains:

4 red balls

3 green balls

5 yellow balls

Then the total number of balls in the bag is 12 balls

The chances of drawing a red ball = number of red balls / total number of balls = 4/12 = 1/3

The chances of drawing a green ball =  number of green balls/ total number of balls = 3/12 = 1/4

Now in probability the phrase OR translate as +

The the chances of drawing a red OR a green ball = chances of red + chances of green = 1/3 + 1/4 = 7/12
