Question

There are 12 face cards in a deck of standard playing cards and 20 even numbered cards (2; 4; 6; 8; 10 in each suit). what is the probability of drawing an even numbered card or a face card when drawing one card.

Answer 1

the probability of drawing a face card is 12/52
the probability of drawing an even number is 20/52
face cards and even numbered cards do not overwrap, so no need to subtract anything
Add up: 12/52+20/52=32/52=0.6154
