Question

A bag contains 30 balls numbered 1 to 30 one ball drawn at random find probability that ball drawn. Find the probability. P(and even, then odd)

Answer 1

Answer:

p(odd numbered balls)=1/2

p(even numbered balls)= 1/2

Explanation:

No. of even nos from 1 till 30 = 15

so, p(even)=15/total no of balls

=15/30

=1/2

similarly,no of odd nos from 1to 30= 15

p(odd)= 15/30

=1/2
