તાસની $52$ પત્તાંની થોકડીમાંથી એક પનું યાદચ્છિક રીતે ખેંચવામાં આવે છે.

કાળા રંગનું હોય તેની સંભાવના શોધો.  

Option A
Option B
Option C
Option D

Solution

Let $F$ be the event in which the card drawn is black.

since there are $26$ black cards in a pack of $52$ cards, $n(F)=26$

$\therefore P(F)=\frac{\text { Number of outcomes favourable to } F}{\text { Total number of possibleoutcomes }}=\frac{n(F)}{n(S)}=\frac{26}{52}=\frac{1}{2}$
