Question

What is the probability of rolling an even number and then an odd number when rolling two number cubes?

Answer 1

Answer:

1) Option D - 36

2) Option C - 9

3) Option C- $\frac{1}{4}$

Step-by-step explanation:

Given : Two dice are rolled and outcome is an even number and then an odd number.

To find :

1)Size of sample spaces

When two dice are rolled total no. of outcomes are  $6^2=36$

Therefore, Option D is correct - 36

2)Number of desired outcomes

Condition is first come even than odd on a dice

Favorable outcomes = (2,1),(4,1),(6,1),(2,3),(4,3),(6,3),(2,5),(4,5),(6,5)

Number of desired outcomes is 9

Therefore, Option C is correct- 9

3)P(first is even and second is odd)

Favorable outcomes =  (2,1),(4,1),(6,1),(2,3),(4,3),(6,3),(2,5),(4,5),(6,5)

Total no. of outcomes = 36

$Probability = \frac{Favorable outcome}{Total outcomes}$

$Probability=\frac{9}{36}=\frac{1}{4}$

Therefore, Option C is correct -$\frac{1}{4}$

Answer 2

Answer:

•Size of sample spaces= 36.

•Number of desired outcomes=9.

•P(first is even and second is odd)=1/4.

•To hard ???- 1st answer is D. 2nd answer is C. 3rd answer is C.

•Still too hard ;-;???- 1st answer is 36. 2nd answer is 9. 3rd answer is 1/4.
