Question

17 cards numbered 1,2,3........17 are put in a box and mixed thoroughly. One person draws as ard from the box. Find the probability that a number on the card is i) divisible by 3 .

Answer 1

Hi friend,

All outcomes are 1,2,3,4.........,17

Number of all possible outcomes = 17

(1) Let E be the event that the number on the drawn card is an odd number.

The favourable outcomes are 1,3,5,7,9,11,13,15,17

Number of all favorable outcomes = 9

P(getting an odd number ) = Favourable outcomes/ Possible outcomes = 9/17

Answer 2

Total numbers divisible by 3 = 3 , 6 , 9 , 12 , 15

Probability of an event =

$\large \boxed{\frac{no.of \: favourable\:outcomes}{total \: no. \: of \: possible \: outcomes} }$

$\implies \: \huge \frac{5}{17} = 0.29$

hence , probability of that number on the card which is divisible by 3 is 0.29
