Pr(queen) = 1/13
Pr(heart) = 25%
Step-by-step explanation:
Part A:
Total cards in a standard deck = 52
from the diagram, there are 4 queens:
1 club queen, 1 spade queen, 1 heart queeen, 1 diamond queen
Probability of getting a queen = number of queens/total number of cards

Part B:
from the diagram, there are 13 hearts:
There are 4 suits, each of them has 13 cards. One of the suits is a heart. This means there are 13 cards with hearts
Probability of getting a heart = number of hearts/total number of cards
