Answer:
The probability is 2/13
Explanation:
To calculate the probability of an event A of happening, we can use the formula:
[tex]P(A)=\frac{favorable\text{ }outcome}{total\text{ }outcome}[/tex]The favorable outcome is the number of 4 and 5 cards in a deck of 52 cards
The total outcome is the total amount of cards.
Since there are one 4 for each symbol in the card (spades, hearts, diamonds and clubs) there are four 4's and applying the same to the 5's, there are four 5's in a deck
Thus, the favorable outcome = 4 + 4 = 8
Now we can write:
[tex]P(4\text{ }or\text{ }5)=\frac{8}{52}=\frac{2}{13}[/tex]
