Detailed Solution

As it is given that a bag contains 6 white balls numbered 1 to 6 and 4 red balls numbered 7 to 10.
Here, total number of balls =10
Let us consider A is an event for getting an odd number ball,
For event A, the probability of an event

P (A)

is represented as,

P (A) = Number of favourable outcomes Total number of outcomes

Balls with odd numbers are A={1,3,5,7,9}
Total number of balls with odd number = 5
Therefore, the probability of getting an odd number ball is

⇒ P A = 510 ⇒ P A = 12

Therefore, probability of getting an odd number ball is given by

12

.
Hence the correct option is 3.
