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

\(P(\textbf{Event}) = \cfrac{\textbf{No. of events in favour}}{\textbf{Total events}}\)
OpenStudy (mertsj):
Remember that we say the probability is the number of successful results over the total number of results.

is it 1/2
OpenStudy (mertsj):
Yes. Very good. 3 even numbers over 6 numbers in all is 3/6 or 1/2
