Answer:
I believe it would be A) 2 + m - 1 + - m
Answer:
C
Step-by-step explanation:
A, B are wrong since 8,795 is a constant, it doesn’t change;
D is wrong since it is the starting cost, not total cost
My method is on a) you would just subtract 12 and 7 which is 5. You can do the rest and then when you get all the answers put them from smallest to largest
Answer:
P(A) = 0.1620 , P(A|B) = 0.0707
Step-by-step explanation:
Total people = 10 + 15 + 20 = 45 , Sophomores = 10, Juniors = 15 , Seniors = 20
P(A) , exactly 3 juniors selected = (15 c 3) (30 c 2) / (45 c 5) = (455 x 435) / 1221759 = 0.1620
P (B) , exactly 2 seniors selected = (20 c 2) (25 c 3) / (45 c 5) = (190 x 2300)/ 1221759 = 0.3576
P(A|B), exactly 3 juniors & exactly 2 seniors selected = P (A∩B) / P (B)
(15 c 3) (20 c 2) / (45 c 5) = (455 x 190) / 1221759 = 0.0707
