Solution

Determining the probability:
Given, the total cards in a pack are $52$ .
So, we have the total number of outcomes $= 52$ .
We know that the total number of hearts in a pack are $13$ .
So, the number of favorable outcomes $= 13$ .
The formula for probability is
$P r o b a b i l i t y = \frac{N u m b e r o f f a v o r a b l e o u t c o m e s}{T o t a l n u m b e r o f o u t c o m e s} \Rightarrow P (h e a r t) = \frac{13}{52} ∴ P (h e a r t) = \frac{1}{4}$
Therefore, when we pick a card from a pack of $52$ , the probability that it will be a heart is $\frac{1}{4}$ .
