Question

You roll a 6-sided die two times. What is the probability of rolling a 4 and then rolling a 2? (Write your answer as a fraction or whole number.)

Answer 1

Answer:

1/36

Step-by-step explanation:

On the first throw, the probability of rolling any particular number, 1 through 6, is 1 out of 6. So the chance of rolling a 4 is 1/6.

On the second roll, your probability of rolling a 2 is 1/6.

The 'trick' is knwoing what to do with those two numbers.

Here's the rule: If events are dependent on one another, you multiply the probabilities.

Any time you see a scenario where X has to happen and then some other thing (X, Y, or whatever) has to happen, the events are dependent.

Probability of rolling a 4 and then rolling a 2 = 1/6 * 1/6 = 1/36

Hope this helps.
