Question

Rahim put 15 slips in a box where each slips numbers are written from 1 to 15.Find the
probability of each of the following.
a. Getting an even number
b. Getting a prime number
c. Getting a multiple of 3

Answer 1

Answer:

Total no. of slips=15

P (E)=Total no. of favourable outcomes/ Total no.

of possible outcomes

a. Total even no.=2,4,6,8,10,12,14

P (an even no.)=7/15

b. Total prime no.=2,3,5,7,11,13

P ( a prime no.)=6/15=2/5

c. Total no. which are multiple of 3=3,6,9,12,15

P (a multiple of 3)=5/15=1/3

Answer 2

Answer:

a) total no. of even no. from 1-15 are 7

so the probability of getting even number is 7/15

b) total prime number from 1to 15 are 7

so ans is 7/15

c) total multiple of 3 are 5 between 1 and 15

so ans is 5/15--1/3
