A card is selected from a pack of $52$ cards. Calculate the probability that the card is black card.
A card is selected from a pack of $52$ cards. Calculate the probability that the card is black card.
Let $F$ be the event in which the card drawn is black.
since there are $26$ black cards in a pack of $52$ cards, $n(F)=26$
$\therefore P(F)=\frac{\text { Number of outcomes favourable to } F}{\text { Total number of possibleoutcomes }}=\frac{n(F)}{n(S)}=\frac{26}{52}=\frac{1}{2}$
