Diamonds are 1/4 of the entire deck, and Clubs are another 1/4. If a card is drawn at random, then there is a 1 in 2 chance that it will be a diamond or a club.

Lets ask Dr. Math to tell us the difference between odds and probability. Based on the good Doctor, the answer would be 26/52 = 1/2 = 50%.
The following is from Dr. Math....
Hi Brett - thanks for writing to Dr. Math.
Let me clarify the difference between probability and odds. The
probability of an event is defined as:
P(x) = (Chances for) / (Total chances)
So, for example, the probability of drawing an ace in a single deck of
52 cards is 4/52 = 1/13 (or about 0.077 = 7.7%).
Odds, on the other hand, are given as:
(Chances for) : (Chances against)
Incidentally, odds of 1:1 would be read as "one TO one", not "one OUT
OF one." (The words "out of" seem to imply total chances, which is
probability, not odds.)
Since (Total chances) = (Chances for) + (Chances against), we can
calculate (Chances against) = (Total chances) - (Chances for). The
odds of drawing an ace in a deck of cards is 4:(52-4) = 4:48 = 1:12.
Notice the difference in the second value; probability uses (Total
chances), but odds use (Chances against). This is why the probability
(if considered as a ratio) and the odds are different.
I hope this helps! If you have any more questions, write back!

the amount of cards is not really relevant in this probability as there are four suits so the likely hood of it being a diamond is one in four. Same for the club and obviously it is 2 in 4 for it being either a club or a diamond.

Half of the cards are either a diamond or club.
Chances (odds) of drawing diamond or club are 1:1 (even money).
In terms of probability -- 50% probability.
