Answer:
7+(((3^2)*((-5)+1))/2
=-11
Step-by-step explanation:
B^2-6b+8 turns into b^2-2b-4b+8 due to the sum product pattern. which then turns into b(b-2) - 4(b-2) and then its (b-4)(b-2)
The probability of a hand of 13 cards contains all 4 of one of the denominations, say Aces, is given by:

The same probability applies to getting all 4 of each of the other denominations.
Therefore the required probability is:

The answer is 0.0343.
If you convert 0.02 kilometers into centimeters, you would get 2,000 centimeters.
