Is my answer correct? Please help!?

Question

For Math, the question is:

What is the probability of a a black card or a card less than 10 (aces not included] in a deck of 52 cards?

I came up with 25/273 but it does not sound right. Is my answer correct? Thanks.

Answer 1

Previous answerer is right except he forgot to excluded aces.  So instead of 18 cards less than 10 there are 16. 26+16 = 42

42/52 = 21/26

Answer 2

No. Black cards would take up 26 of the cards. Cards less than 10 but not black take up 18. 26+18=44. there is a 44/52 chance and You simplyfy it into 11/13
