The probability of drawing two balls of the same color are
Answer: (Option B).
Given Data:
8 white Ball
6 Red Ball
Step 1:
Let us assume the probability is 100%.
So you draw one ball. The probability that it's red is
You draw again.
Probability (Second red)
Step 2:
The probability of drawing two red balls is therefore
Now, suppose instead of a red on the first draw you got white.
The probability of this is
Step 3:
Given the first ball is white, the probability of drawing a second white is
P (two whites) =
Step 4:
P (Two balls of same color) =
