Answer:a) 54/55
b) 100/110
c) 99/110
Step-by-step explanation:
a)Probability of ordering 4= 9/12×3/11×2/10×1/9 = 54/11880
Probability of 4 good units= 4 × 54/11880
= 216/11880
1/55
1-(1/55) = 54/55
b)Probability of 2 good units= 2 × 54/(11880)
= 108/11880
= 1/110
1- (1/110)= 100/110
c) Probability of exactly 2 units not good= 1 -(100/110) =99/110

9.90=p (.06)(3)
9.90=p(.18)
9.90/.18=p.18/.18
55=p
I put in $55 into the account when I opened it.
You divide 36 by 9 so w equals 4
1 by 8 rectangle... that is a area of 8 square inches.
the greatest is 4 by 5 that is a area of 20 square inches.
The difference is 12
A). Diameter is the answer
