Question

80 bulbs are selected at random from a lot and their life time (in hours) is
recorded in the form of a frequency table given. One bulb is selected at
random from the lot. Find the probability that it’s life is :
1150 hours

Answer 1

Answer:

0

Step-by-step explanation:

Total bulb in a lot,n (S)

Number of bulbs whose life time is 1150, n(E) =0

Probability that its life time is 1150 hrs=n(E)/n(S)

=0/80=0

Henve the probability that its life time is 1150 is 0.
