Question

You roll a six-sided die twice. What is the probability of rolling an even number and then an odd number? A) 1 16 B) 1 8 C) 1 4 D) 1 2

Answer 1

Answer:

The probability of rolling an even number and then an odd number is $\frac{1}{4}$ Option C is correct

Solution:

Given, You roll a six-sided die twice.  

We have to find what is the probability of rolling an even number and then an odd number?

We know that, rolling single die two times is equivalent to two dice rolling at a time.

$\text { Now, probability of an event }=\frac{\text { number of favourable outcomes }}{\text { total possible outcomes }}$

So, now, total possible outcomes = 6 x 6 = 36

And, number of favourable outcomes = 3 even on 1st die x 3 odd on 2nd die = 3 x 3 = 9

Then, probability = $\frac{9}{36} = \frac{1}{4}$

Hence, the probability of given condition is $\frac{1}{4}$  and option c is correct.
