Question

A box contains paperslips writing even numbers lessthan 10 and another contains perfect square less than 20. If one slips from each is takenout a)Write the possible pairs of numbers? b)Calculate the probability of both being perfect squares? ​

Answer 1

Answer:

If we draw one slip from each box, total number of possible pairs=10×10=100

Prime numbers between 1 and 10 are 2,3,5 and 7.

Thus, there are 4 prime numbers in each box.

⇒ Number of pairs such that two slips are prime =4×4=16

Thus, probability that both the slips are prime =10016=254
