The probability of being dealt a five card hand that is two pair from a well shuffled standard deck of cards is 40.
According to the statement
I have 10 starting cards, from Ace to 10, and 4 suits,
and by this way we get the 40 subsets and because of these subsets there is a probability becomes 40.
So, The probability of being dealt a five card hand that is two pair from a well shuffled standard deck of cards is 40.

Step-by-step explanation:
The time taken to fill the tank using a pump that pumps 25L per minute
is 30.4 minutes
Given that A 1000L tank now contains 240L of water and asked the time taken to fill the tank using a pump that pumps 25L per minute.
The amount of water that can be filled in tank=760L
Given that a pump that pumps 25L per minute ,
The time required to fill 760L {if a pump that pumps 25L per minute }=
The time required to fill 760L {if a pump that pumps 25L per minute }=30.4 minutes
Therefore,The time taken to fill the tank using a pump that pumps 25L per minute is 30.4 minutes
