A shopkeeper sells three types of flower seeds `A_1, A_2 and A_3` . They are sold as a mixture whereas the proportions are 4:4:2 respectively. The germination rates of the three types of the seeds are 45%, 60%, 35%. Find the probability
of a randomly chosen seed to germinate.

In a tape recorder factory, three machines A, B and C produced 25%, 35% and 40% respectively. The percentage of defective output of these machines are 5%, 4% and 2% respectively. A tape recorder is selected at random and is found to defective. Find the probability that tape recorder is produced by machine B .

ln a tape recorder factory, three machines A, B and C produced 40%, 30% and 20% of total production. The percentage of the defective output of these machines are 2%, 3% and 4% respectively. A tape recorder is selected at random and found to be defective. Find the probability that tape recorder is produced by machine C.

In a tape recorder factory, three machines A, B and C produced 50%, 30% and 20% of total production. The percentage of the defective output of these machines are 3%, 4% and 5% respectively. A tape recorder is selected randomly and found to be defective, find the probability that it is produced by machine A.

P= A^3. B^(1/2) . C^1 . If percentage errors in A, B and C are 1, 2 and 4 respectively, then find the percentage error in P.

Three machines E_1, E_2, E_3 in a certain factory produce 50%, 25% and 25% respectively of the total daily output of electric tubes. It is known that 4% of the tubes produced by each of machines E_1 and E_2 are defective, and that 5% of those produced on E_3 are defective. If one tube is picked up at random from a day's production, calculate the probability that it is defective.

There are three urns containing 2 white and 3 black balls, 3 white and 2 black balls, and 4 white and 1 black balls respectively. There is an equal probability of each urn being chosen. A ball is drawn at random from an urn chosen at random and is found to be white. find the probability that the ball has bee drawn from the second urn.

In a species the weight of newborn ranges from 2 to 5 kg. 97% of the newborn with an average weight between 3 to 3.3 kg survive whereas 99% of the infants born with weights from 2 to 2.5 kg or 4.5 to 5 kg die. Which type of selection process is taking place?

In a town of 10,000 families, it was found that 40% families buy newspaper A, 20% by newspaper B and 10% buy newspaper C. Further 5% buy A and B, 3% buy B and C, 4% buy A and C. If 2% of the families buy all the three newspaper find: Number of families that buy none of the three newspapers.
