Answer:
Step-by-step explanation:
Given that a box contains 45 light bulbs, of which 36 are good and the other 9 are defective.
Probability for any one to be defective as of now is ![\frac{36}{45} =0.80](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B45%7D%20%3D0.80)
a) ![P(E) = 0.80](https://tex.z-dn.net/?f=P%28E%29%20%3D%200.80)
b) After I draw we have 35 good ones and 9 defective
P(F/E) =![\frac{35}{44} \\=0.796](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B44%7D%20%5C%5C%3D0.796)
c) P(G/EF)
This is the probability for iii bulb to be good given I and II are goog.
Once I and ii are good we have 43 bulbs with 34 good ones
![P(G/EF) =\frac{34}{43} \\=0.7907](https://tex.z-dn.net/?f=P%28G%2FEF%29%20%3D%5Cfrac%7B34%7D%7B43%7D%20%5C%5C%3D0.7907)
