Question

17 cards numbered 1, 2, 3, 4, ..., 17 are put in a box and mixed thoroughly. A card is drawn at random from the box. Find the
probability that the card drawn bears (i) an odd number (ii) a number
divisible by 5.​

Answer 1

Answer:

the probability for first

1 3 5 7 9 11 13 15 17

we can see here are 9 numbers. so the probability for it will be 9/17

now for an odd number. a number divisible by 5

here are 3 numbers

so the probability will be 3/17
