There are [tex]13[/tex] of each suit in a deck of [tex]52[/tex] cards.
This means the probability of drawing a diamond card is [tex]\frac{13}{52}[/tex]. You can divide the numerator and denominator each by [tex]13[/tex] to simplify. [tex]\frac{13}{52} \div \frac{13}{13} = \boxed{\frac{1}{4}}[/tex]
Since there are the same number of clubs as there are diamonds, the probabilities are the same.
