Question

One card is selected from a well shuffled deck of $52$ cards. Find the probability of getting a spade.

Answer 1

Number of favourable outcomes i.e. ‘a spade’ is $13$ out of $52$ cards.
Therefore, probability of getting ‘a spade card’
$P=$ Number of favorable outcomes /Total number of possible outcome
$=\frac{13}{52}$
$=\frac{1}{4}$.
