Question 850608
In a standard deck, the red cards are hearts and diamonds. There are "8 hearts, 8 diamonds", so 8+8 = 16 red cards.


There are "8 hearts, 8 diamonds, 6 spades, and 6 clubs", so 8+8+6+6 = 28 cards total


The experimental probability is the number of things we want over the number of things total, so...



experimental probability = (# of things we want)/(# of things total)


experimental probability that card is red = (# of red cards)/(# of cards total)


experimental probability that card is red  = 16/28


experimental probability that card is red  = 4/7 ... make sure to reduce all fractions



So the answer is <font color="red">4/7</font>
