6% of 124...." of " means multiply
.06(124) = 7.44
Answer: .13
Step-by-step explanation:
63/100=0.63
5/10=0.50
=.13
I took 63 and divided it by 100 to get .63 and took 5 and divided it by 10 to get .50 so I took them and subtracted them to get .13
The probability of picking 2 white balls and 1 black ball is 0.154
<h3>How to determine the probability?</h3>
The given parameters are:
- Number of balls, n = 20
- White = 12
- Black = 8
When each ball is selected, the total number of ball decreases by 1 and the type of ball also decreases.
So, the probability is represented as:
P(2 white and 1 black) = White/n * White - 1/n - 1 * Black//n - 2
Substitute known values
P(2 white and 1 black) = 12/20 * 11/19 * 8//18
Evaluate
P(2 white and 1 black) = 0.154
Hence, the probability of picking 2 white balls and 1 black ball is 0.154
