Final answer:
The probability of selecting a heart card from a deck is 1/4, as there are 13 hearts out of 52 cards.
Step-by-step explanation:
The student's question is about determining the probability of selecting a heart card from a standard deck of 52 playing cards. Since each suit (hearts, clubs, diamonds, spades) contains 13 cards, the probability of selecting a heart is simply the number of heart cards (13) divided by the total number of cards (52). Therefore, the probability of selecting a heart is 1/4 or 13/52, which simplifies to 1/4 since there are 4 suits in total and all suits have an equal number of cards.
