Question

12. What is the probability of
even number in first ten
natural numbers?​

Answer 1

Answer:

Sample space :

1,2,3,4,5,6,7,8,9,10

Total number of observations=10

(a) probability of even number

Favourable numbers are 2,4,6,8,10

thus there are 5 favourable events

Hence probability of even number

=5/10

=1/2 or 0.5

(b) prime number

2,3,5,7 are prime numbers from 1–10

Thus there are 4 favorable numbers.

Probability=4/10

=2/5 or 0.4
