John throws a fair 6-sided die. What is the probability he will get a multiple of 2?

OpenStudy (anonymous):

how many multiples of two are there on a six sided die?

OpenStudy (anonymous):

A 1/6 B 1/3 C 1/2

OpenStudy (anonymous):

the number of multiples of 2, divided by the total number of sides

OpenStudy (anonymous):

?

OpenStudy (mertsj):

What are the numbers on a number cube?

OpenStudy (anonymous):

1 -6

OpenStudy (mertsj):

Are any of them even?

OpenStudy (anonymous):

2 4 6

OpenStudy (mertsj):

So there are 3 even numbers?

OpenStudy (anonymous):

YEA

OpenStudy (mertsj):

And 6 numbers in all?

mathslover (mathslover):

caps off please.. :)

OpenStudy (anonymous):

yea

OpenStudy (mertsj):

So if there are three even numbers and 6 numbers in all, what is the probability that I will roll an even number?

OpenStudy (anonymous):

1/3

OpenStudy (mertsj):

I think you may have reduced the fraction incorrectly. Try again.

OpenStudy (mertsj):

Wouldn't that be a 3 out of 6 chance?

OpenStudy (anonymous):

1/6

mathslover (mathslover):

\(P(\textbf{Event}) = \cfrac{\textbf{No. of events in favour}}{\textbf{Total events}}\)

OpenStudy (mertsj):

Remember that we say the probability is the number of successful results over the total number of results.

OpenStudy (anonymous):

is it 1/2

OpenStudy (mertsj):

Yes. Very good. 3 even numbers over 6 numbers in all is 3/6 or 1/2
