Question

An ordinary die is rolled. What is the probability that the number of lots on its upper face is an even number?​

Answer 1

Step-by-step explanation:

an die is rolled the sample space will be

s = (1,2,3,4,5,6)

n(s) = 6

let event A be that the number on upper face is an even number

A= ( 2,4,6)

n(A) = 3

p(A) = n(A) / n( s)

p(A) = 3 / 6

P(A) = 1/2 = 50%
