# a number x is selected from the numbers 1,2,3 and then second number y is selected from numbers 1,4,9. what is the probability that the product xy of the two numbers will be less than 9?2.. cards marked with numbers 13,14,15....,60 are placed in a box and mixed. one card is drawn at random from the box. find the probbility that the sum of the digits on the card drawn is 5?3.. on tossing a die the probability of getting an odd number or the number les than 4 is?

Que.2. Given: Cards are marked 13, 14,15,.................,60

Total no. of cards=48

Hence to draw one card, no. of possible cases=48

Let A be the event of getting the sum of the digits 5.

the sum of the digits can be 5 in the only following cases:

when the drawn number is one of 14,23,32,41,50.

so the no. of favourable cases are 5

Que.3. When a die is thrown, total no. of possible cases are 6

Let A be the event of getting an odd number or a number less than 4.

then A={1,3,5,2}

the no. of favourable cases are 4

Probability of getting an odd number or a number less than 4 is
