Question

A box contains 10 paper slips numbered 1 to 10 and another box contains 5 paper slips

numbered 1 to 5 , One slip is taken from each box.

(a) How many possible pairs are there.

(b) What is the probability of both the numbers even.

(c) What is the probability of both the numbers odd.

(d) What is the probability of one odd and the other even.

(e) What is the probability of both being the same number ?​

Answer 1

Answer:

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

Prime numbers between 1 and 10 are 2, 3, 5 and 7. → Number of pairs such that two slips are

Thus, there are 4 prime numbers in each

box.

prime = 4 x 4 = 16

Thus, probability that both the slips are

16 100 4 25 prime
