Question

You roll a 6-sided die twice. What is P(1, less than 3)? Simplify

your answer and write it as a fraction or whole number.

Answer 1

Total sample space

• {1,2,3,4,5,6}

So

P(1)

• 1/6

P(<3)

• 2/6=1/3

P(1,<3)

• 1/6×1/3
• 1/18

Answer 2

• 1/18

Explanation:

Probability of 1 is 1 out of 6:

• 1/6

Probability of less than 3 is:

• 1 or 2 out of 6 = 2/6 = 1/3

P(1, less than 3) is

• 1/6* 1/3 =
• 1/18
