Answer:Pr( Bulb does work)= 0.9993
Step-by-step explanation:
From my own experience, I would say, 1 out of 1500times I turn on the light, the bulb does not work.
My subjective probability estimate that the bulb does not work =1/1500
And probability the bulb does work=
1- 1/1500
Pr( Bulb does work)= 0.9993
Therefore the subjective probability that the bulb does work is 0.9993
