## Answer ( 1 )

1. The probability of selecting a defective bulb is 0.16.
Given: 8 Bulbs are defective out of 50 bulbs. To find the probability that a randomly selected item is defective.
What is probability?
Probability shows the possibility of how likely an event is happening to occur out of all the possibilities.
Let’s solve the problem:
Total number of video recorders: 50
The sample space n(S) = 50
Number of defective bulbs: 8
Let E be the event of selecting a defective bulb.
Then n(E) = 8
Therefore, the probability of selecting a defective bulb: Number of defective bulbs / Total number of bulbs
=> n(E) / n(S)
=> 8 / 50
=> 0.16
Hence the probability of selecting a defective bulb is 0.16.
