The bulbs manufactured by a company gave a mean life of 3000 hours with standard
deviation of 400 hours. If a bulb is selected at random, what is the probability it will
have a mean life less than 2000 hours?
Question:
1) Calculate the probability.
2) In what situation does one need probability theory?
3) Define the concept of sample space, sample points and events in context of
probability theory.
4) What is the difference between objective and subjective probability?

Mr Sehwag invests Rs 2000 every year with a company, which pays
interest at 10% p.a. He allows his deposit to accumulate at C.I. Find
the amount to the credit of the person at the end of 5th year.

The price P per unit at which a company can sell all that it produces
is given by the function P(x) = 300 — 4x. The cost function is c(x)
= 500 + 28x where x is the number of units produced. Find x so that
the profit is maximum.
