Answer:
He sold 12 chocolates for 1 Re.
Step-by-step explanation:
He bought 15 chocolates for 1 Rupee
He sold for a profit of 25%
Sale price = profit + cost price
SP= 25%of 1 + 1 Re
SP = 0.25*1+ 1
SP = 1.25 Rs
He sold 15 chocolates fro 1.25 Rs
Chocolates Rupees
15 1.25
x 1
Applying cross product
x*1.25= 15*1
x= 15*1/1.25
x= 12
He sold 12 chocolates for 1 Re.
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
