Question

You roll a 6-sided die two times.

What is the probability of rolling a 1 and then rolling a factor of 9?

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

Answer 1

Answer:

The answer will always be 1/36 with 2 dice for any numbers under 7

each.

The numbers go like this

rolling 1 from two dice = 1/6  x  1/6 = 1/36

Step-by-step explanation:

Probability Table of Rolling Two Dice

The possible outcomes of rolling two dice are represented in the table below. Note that the number of total possible outcomes is equal to the sample space of the first die (6) multiplied by the sample space of the second die (6), which is 36.

Answer 2

The probability of rolling a 1 and then rolling a factor of 9 is 1/36

What is probability ?

Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event.

How to calculate the probability?

Probability can be calculated by simply dividing the number of favorable outcomes by total number of outcomes.

Step-by-step explanation:

• Probability of rolling a 1  P(E1)= 1/6
• Probability of rolling a factor of 9 is 3 P(E2) = 1/6

Hence probability of rolling a 1 and then rolling a factor of 9

P(E1 x E2) = 1/6 x 1/6 = 1/36

Hence , The probability of rolling a 1 and then rolling a factor of 9 is 1/36
