Answer:
31/98
Step-by-step explanation:
31 motor scooters
67 other vehicles
31 + 67 total vehicles
31 + 67 = 98
The probability is motor scooters/total vehicles
31/98 is the answer.
Answer:
0.0467
Step-by-step explanation:
Probabilty of being defective is ![\frac{3}{190}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B190%7D)
So probability of being good is ![\frac{187}{190}](https://tex.z-dn.net/?f=%5Cfrac%7B187%7D%7B190%7D)
Now,
Probability that all 3 of them are good is:
![\frac{187}{190}^{3}=0.9533](https://tex.z-dn.net/?f=%5Cfrac%7B187%7D%7B190%7D%5E%7B3%7D%3D0.9533)
Now, to find probability of rejection, we subtract the now found probability from 1. Thus, we have:
1 - 0.9533 = 0.0467
