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
The table isn’t shown so I cant tell
Answer:
2,850
Step-by-step explanation:
4.25 x 9 = 38.25
4.25 x 13 = 55.25
4.25 x 12 = 51
13.70 x 92 = 1260.4
3.28 x 130 = 426.4
8.06 x 126 = 1015.56
all totals would equal 2,846.86, which to the nearest would be $2,850
