(a) 1

(b) 0

(c) 0.23

(d) 0.5

The question was asked by my college director while I was bunking the class.

My doubt stems from Theoretical Approach to Probability in chapter Probability of Mathematics – Class 10

Answer 1

The correct option is (b) 0

Easy explanation: Selecting 8 blue balls from 10 green balls is an impossible event. An event that doesn’t occur in any possible scenario is called an impossible event. The probability of an impossible event is always zero.
