Question

Can you please help me out

Answer 1

Ok, here we have an probability problem:

So we are going to calculate first their occurrences separately and then their union.

Probability of rolls an even number: 1/2 (2.4.6)

Probability of rolls an odd number: 1/2 (1.3.5)

Probability of get first an even number and then an odd number:

`(1)/(2)\cdot(1)/(2)=(1)/(4)`

The probability of get first an even number and then an odd number is 1/4.

Option A.
