Answer:
2/5
Step-by-step explanation:
There are 2 white and 4 yellow = 6
P(yellow) = yellow /total = 4/6 = 2/3
We keep the ball
Now there are 2 white and 3 yellow = 5
P(yellow) = yellow /total = 3/5
P ( yellow, keep, yellow) = 2/3 * 3/5 = 2/5
We are given 4 yellow balls and 2 white balls. In total, this adds up to 6.
Divide the number of yellow balls to the total number of balls:
4/6 -> 2/3
We are also given 3 yellow and 2 white.
Divide the number of yellow balls to the total number of balls:
3/5
Divide both fractions together:
3/5 * 2/3 = 6/15 = 2/5
Best of Luck!
