Answer:
$51.33
Step-by-step explanation:
Everything is off 65% so that means that $15.40 if 35% of the original price(100%-65%)
Set up Equation:
Simplify:
Multiply the first numerator by the last denominator and the first denominator by the last numerator
Divide 3 by both sides:
x= 51.33
The probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4 is .
Solution:
Total number of outcomes N(S) = 36
Let A be the sum that is a multiple of 6 and
B be the sum that is a multiple of 4.
Sum that is a multiple of 6 = (1, 5), (2, 4), (3, 3), (4, 2), (5, 1), (6, 6)
N(A) = 6
Sum that is a multiple of 4 = (1, 3), (2, 2), (2, 6), (3, 1), (3, 5),
(4, 4), (5, 3), (6, 2), (6, 6)
N(B) = 9
Probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4:
(Make the denominator same)
Hence the probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4 is .
