One card is drawn from a well-shuffled deck of 52 cards. Find the probability that the card be an ace.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 1/13
Probability is the number of favourable outcomes divided by the total number of outcomes. A well-shuffled deck makes all 52 cards equally likely, and the deck has 4 aces, one in each suit.
\(\displaystyle P(\text{ace})=\frac{4}{52}=\frac{1}{13}\)
