This is a permutation because order does not matter, combinations are when order does matter. To determine how many unique combinations, permutations, there are for this problem, we need to use the "n choose k" formula:
p=n!/(k!(n-k)!), where n=number of elements to choose from, and k=number of choices made, in this case:
p=35!/(3!(35-3)!)
p=35!/(3!32!)
p=6545
So there are 6545 unique ways that a president, vice president, and secretary can be chosen from 35 members.
If William has 3^3 baseball cards that means he has 3x3x3 baseball cards which is 27. 4^3 football cards is 4x4x4 so he has 64 of those. 64 + 27 = 91 so that’s how many cards he has in total
Answer:
The answer is D
Step-by-step explanation:
1/5 = 0.2
0.2x3 = 0.6
0.2x5=1
1. subtraction expression 8-3
the difference multiplied by 4
expression 2 is 4 times as large as expression 1
