Answer:
Probability will be 0.5779
Step-by-step explanation:
Number of tablets n = 19
Probability of defect rems that is p = 0.03
Here number of trials is fixed and probability of success = 0.03
Here p = 0.03
So q = 1 - p = 1 -0.03 = 0.97
By using binomial distribution
Probability is given by ![^nC_rp^rq^{n-r}](https://tex.z-dn.net/?f=%5EnC_rp%5Erq%5E%7Bn-r%7D)
So P(0 or 1) = ![^{19}C_0{0.03}^0{0.97}^{19-0}+^{19}C_1{0.03}^1{0.97}^{19-1}=0.5606+0.0173=0.5779](https://tex.z-dn.net/?f=%5E%7B19%7DC_0%7B0.03%7D%5E0%7B0.97%7D%5E%7B19-0%7D%2B%5E%7B19%7DC_1%7B0.03%7D%5E1%7B0.97%7D%5E%7B19-1%7D%3D0.5606%2B0.0173%3D0.5779)
Answer:
7 cars
Step-by-step explanation:
The computation of the number of cars to be filled is shown below:
A car that is 90% full and the total people is 20 so 90% would be
= (.90)(20)
= 18
A car that is 65% full and the total people is 20 so 65% would be
= (.65)(20)
= 13
Now
Total number of people = (5)(18) + (3)(13).
= 129
Now the number of cars to be filled is
= 129 ÷ 20
= 6.45
= 7 cars
