In this lesson, we will learn how to determine the sample space and the probability.

Q1:

Given that the sample space is the set of all 2-digit numbers whose digits are different and belong to , write the event that the number is odd.

Q2:

What is the probability of choosing at random, two numbers which sum to 9, from the set { 1 , 5 , 7 , 8 } ? You are allowed to pick the same number more than once.

Q3:

I write a two-digit number by randomly picking each digit from the set { 2 , 4 , 8 } , where a digit can be repeated. What is the probability that the product of the two digits is 32?
