Answer: One doll can be finished with 5 buttons.
Step to step explanation:-
Given statements : A machine makes 5 buttons at a particular time.
The number of buttons each doll shirt gets= 5
Therefore, the number of dolls finished with 5 buttons= 1
Therefore, if a machine makes 5 buttons at a particular time and each doll shirt gets 5 buttons then only one doll can be finished with 5 buttons.
Answer:
a) 0.0184
b) 0.1829
Step-by-step explanation:
a) With geometric distribution you can measure the number of trials until the first success, that is, a defective chip is found, as follows:
P(x = k) = p*(1-p)^(k-1)
This means: probability to find exactly 1 defective in k trials, p is the probability to find a defective chip, which is equal to 0.02, and the number of trials are k = 5. Replacing:
P(x = 5) = 0.02*(1-0.02)^(5-1) = 0.0184
b) If you want the probability of 1 success within k trials, compute:
![P(x](https://tex.z-dn.net/?f=%20P%28x%20%3C%3D%20k%29%20%3D%20%5Csum_%7Bi%3D1%7D%5E%7Bk%7D%20p%20%281%20-%20p%29%5E%7Bk-1%7D)
Replacing with k = 10
![P(x](https://tex.z-dn.net/?f=%20P%28x%20%3C%3D%2010%29%20%3D%20%5Csum_%7Bi%3D1%7D%5E%7B10%7D%200.02%20%281%20-%200.02%29%5E%7B10-1%7D%20%3D%200.1829)
The answer is 9 because 8-3=6
