First doughnut:
P(C)=11/24
Second donough given the first was custard-filled:
P(C)=(11-1)/(24-1)=10/23
Probability for both of them to be custard-filled, multiply the two probabilities
11/24*10/23=55/276

Answer: 35 minutes
Step-by-step explanation:
Step-by-step explanation:
For us to solve the question, we have to calculate the amount of gallons of water that is drained every minute. This will be:
= (1320 - 1040) / (9 - 2)
= 280/7
= 40 gallons per minute
Since we are told that 1,320 gallons of water remain in the pool after 2 minutes. This means that the total water in the pool at the beginning was:
= 1320 gallons + (40 × 2)
= 1320 gallons + 80 gallons
= 1400 gallons
The time taken for the pool to be completely drained will be:
= Total water in pool / Gallons drained per minute
= 1400 / 40
= 35 minutes
