Answer: 220
Step-by-step explanation:
When we wanto to create a group of K elements for a set of N elements (where the order of the K elements does not matter, so we do not considerate the permutations of the K elements), the number of possible combinations is:
Here N = 12 and K = 3
So there are 220 possible combinations
Answer:
1/36
Step-by-step explanation:
The probability that the first winner lives in Gaston is 2/9. The probability that the second winner lives in Gaston is 1/8, the number of remaining Gastonites divided by the total number remaining in the pool.
Then the probability of both of these events is the product:
P(2 from Gaston) = (2/9)(1/8) = 2/72 = 1/36
The probability both are from Gaston is 1/36.
Answer:
102
Step-by-step explanation:
Each triangle will have a perimeter of 3. When joined, the outside triangles will have 2 sides showing, or 2 inches. The middle 98 will only have one free side, or one inch. This means that 98*1 + 2*2 = 102
The quantities in the proportion you give add to 16 pounds, of which 2 pounds are cement. That is, cement constitutes 1/8 of the total weight.
For each yard of concrete, 4000 lb/8 = 500 lb of cement are used.
For 12.5 yards of concrete, 12.5 * 500 = 6,250 pounds of cement will be used.
_____
"yard" in this case is shorthand for "cubic yard".
