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
I can’t answer this question because I can’t see the model
X + 3 = 0
2x - 1 = 0
It would be D.
Answer:
9.983796
Step-by-step explanation:
Every time, it becomes smaller by 5/2 (6 divided by 5/2 is 12/5.... 12/5 divided by 5/2 is 24/25)
So, the first seven terms are 6, 2.4, 0.96, 0.384, 0.1536, 0.06144, 0.024756. Add them together and your answer would be 9.983796
Pleaseeee mark me brainliest :))
