Cycle tyres are supplied in lots of 10 and there is a chance of 1 in 500 tyres to be defective. Using Poisson's distribution the approximate number of lots containing no defective tyres in a consignment of 10,000 lots is e^-0.02=0.9802

Cycle tyres are supplied in lots of 10 and there is a chance of 2 in 100 tyres to be defective . Using Poisson's distribution the approximate number of lots containing no defective tyres in a consignment of 1000 lots is e^-0.2=0.819

(i) A shop-keeper buys a particular type of electric bulbs from three manfacturers M_(1) , M_(2) and M_(3) . He buys 25% of his requirement from M_(1) , 45% from M_(2) and 30% from M_(3) . Based on the past experience, he found that 2% of type M_(3) bulbs are defective, where as only 1% of type M_(1) and Type M_(2) are defective . If a bulb chosen by him at random is found defective find the probability that it was of type M_(3) . (ii) In a certain college, 25% of the boys and 10% of the girls are studying mathematics.
