Question

A dice is rolled 3 times what is the probablity of getting at least one even number

Answer 1

Answer:

answer is 1/2. as dice have half even half odd

Answer 2

Step-by-step explanation:

In a 6 sided die there are 3 even and 3 odds, so the probability of picking even numbers = 3/6=1/2

Similarly the probability of picking odd numbers = 3/6==1/2

Now

six-sided die is rolled three times and the probability of picking an even number =

$\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{8}$

But this is only one possibility and the dice is rolled three times i.e. it can have :

1.even,odd,odd ;

2.odd,odd,even

3.odd, even , odd

Therefore probability of picking an even number in 3 rolls: 3∗1/8=3/8=0.375
