Because the drawings are independent, the probability is the product of the probabilities of winning each drawing:
1/C(56, 3) × 1/23 = 1/(27,720×23) = 1/637,560
_____
C(n, k) = n!/(k!(n-k)!)
C(56, 3) = 56*55*54/(3*2*1) = 56*55*9
The answer is going to be 19.505? hope that helped
Can anyone else figure this out
Answer:
The distance between (5,8), and (-1,4) is (6, 12).
Step-by-step explanation:
All you have to do is think of it as a line. -1 is here, to get to positive 5, you must move 6; -4 is there, to get to positive 8, you must move 12.
Answer:
Kyle would save more using his 15% off of $1000 coupon.

$150 is the amount the 15% coupon took off.
$850 is the amount Kyle will pay.
