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

So each lap is about 10 minutes witch makes it possible to be 5
34.30. I think this is the answer.
Answer:
9/2 or 4.5
Step-by-step explanation:
15/4x6/5 = 3/2x3 = 9/2
Step-by-step explanation:
n (U)=2000
n (A)=50% of 2000
=(50÷100)×2000
= 1000
n( B) = 40%
= (40÷100)×2000
= 800
n(AuB)(compliment) = 15%
=(15÷100)×2000
=300
