The answers are

A.
B.
C.
D.


So now my answer is 1/18, but its not on there, but 5/90 is and thats the unsimplified version

The probability of taking an odd card from initial deck is 5/10 (or 1/2), then the probability to take a 2 from the remaining deck is 1/9. Either way we get 5/10 * 1/9 = 5*90 or 1/18 which is the same number.

Thank you so much, hopefully it wont be counted as a wrong answer

If you had only the four choices listed, then you had to choose 5/90 as it is equal to the right answer.
