In a standard deck of cards, there is 52 cards.
Face cards includes: Jack, Queen, King, and 1
We are also including cards worth: 3
There are 4 of each cards.
J = 4
Q = 4
K = 4
1 = 4
3 = 4
Add all of them up.
4 + 4 + 4 + 4 + 4 = 20
There are 20 cards that have a face card or is a 3.
Now place the amount you got with the total.
20/52 is the fraction probability.
Divide 20 with 52
20/52 = 0.3846
0.3846 is the decimal probability (or rounded = 0.38)
To find the percentage probability, move the decimal point to the right two place values
0.3846 becomes 38.46%.
hope this helps!
