**CFA Practice Question**

Consider an experiment that consists of removing a card from a deck and identifying its suit. A deck has 52 cards: 13 diamonds, 13 hearts, 13 spades, and 13 clubs. Each card has an equal probability of being selected. What is the probability that a card selected randomly is a heart?

B. 0.07

C. 0.25

A. 0.02

B. 0.07

C. 0.25

Correct Answer: C

The probability of selecting each card from the deck randomly follows a uniform distribution. Given that there are 52 different cards, each card has a 1/52 chance of being selected. If we are only interested in selecting a card of a certain suit, then we must add the probabilities for all the cards with that suit. This probability is 13/52 = 0.25.
