Simplify 8C5-
I have no Idea how to solve this, if someone could help? The choices are:
A. 6,720
B. 336
C. 56*?
D. 10
8C5 = 8C3 = 8*7*6 / 1*2*3 = 56
Note that 8C5 = 8C3 because
8*7*6*5*4/1*2*3*4*5 = 8*7*6/1*2*3
The extra two factors 4*5 cancel out.
Steve is correct, 8C5 = 8C3 = 8*7*6 / 1*2*3 = 56
Answer: c.56
you guys could have just said yes or no to his question of is his answer correct
The number of possible groups of 3 players that can be selected from the 12 players on the team is given by the combination formula:
12C3 = 12!/(3!(12-3)!) = 220
Therefore, there are 220 possible groups of 3 players that can be selected from the 12 players on the team for the team photo.
It makes me so happy that y'all agreed on one answer. :)

Bot answer:
iris plans to plant 3 dofferent tupes of flowers in her garden. she has 5 different tupes of flower seeds to choose from. how ,any combinations are possible
There are 10 possible combinations of flower seeds that Iris can plant in her garden. This can be calculated using the formula for combinations, which is:
nCr = n! / (r! * (n - r)!)
Where n is the total number of items (in this case, 5 types of flower seeds) and r is the number of items being chosen (in this case, 3 types of flower seeds).
So, applying the formula, we get:
nCr = 5! / (3! * (5 - 3)!)
nCr = 5! / (3! * 2!)
nCr = (5 * 4 * 3 * 2 * 1) / ((3 * 2 * 1) * (2 * 1))
nCr = 10
Therefore, there are 10 possible combinations of flower seeds that Iris can plant in her garden.
