(5ac+10ab)+(-2c^2-4bc)
5a(c+2b) -2c(c+2b)
(5a-2c) (c+2b)
P(x < a) = 0.6985
Z score at p = 0.6985 using excel = NORM.S.INV(0.6985) = 0.5201
Answer:
1 / 3
Step-by-step explanation:
Bag 1 :
Yellow = 3
Green = 2
Red = 1
Total = 3 + 2 +1 = 6
Bag 2 :
Yellow = 3
Green = 3
Red = 3
Total = 3 + 3 + 3 = 9
P(not yellow from bag 1) = (green + red) / total = 3 /6 = 1/2
P(not yellow from bag 2) = (green + red) / total = 6/9 = 2 /3
P(neither is yellow) = 1/2 * 2/3 = 2 / 6 = 1/3
