Question

17. What is the probability of selecting an even number
from the numbers 10 to 20 inclusive?

Answer 1

Answer:

s={10,11,12,13,14,15,16,17,18,19,20}

n(s)=11

let event A be the event that the number selected is a even number

A={10,12,14,16,18,20}

n(A)=6

p(a)=$\frac{n(A)}{n(s)}$=6/11

probability will be 6/11
