Let U be the universal set, where U=(1,2,3,4,5,6,7,8,9)let sets A and B. be subsets of U, whereA=(2,3,8,9) and B=(1,2,3,5)

(A U B) = {1, 2, 3, 5, 8, 9}
(A U B)^c = {4, 6, 7}
A^c = {1, 4, 5, 6, 7 }
B^c = {4, 6, 7, 8, 9}
A^c ∩ B^c = {4, 6, 7}
8 + 3(4 + 5)
8 + 3(9)
8 + 27 = 35
Answer:21 cm
Step-by-step explanation: The circle's circumference is 84 cm. 84 / 4 = 21. Therefore the length of the arc XY is 21 cm.
Answer:
For 3 quarters, the probability that all 3 quarters will land heads up is ;
P = 1/2 × 1/2 × 1/2 = 1/8
P = 1/8
Step-by-step explanation:
The probability that one quarter will land heads up is 1/2.
For 3 quarters, the probability that all 3 quarters will land heads up is ;
P = 1/2 × 1/2 × 1/2 = 1/8
P = 1/8
