In a deck of playing cards without a king, what is the probability that one card is a heart at random? What is the probability that the heart will be next if you put this outside?

The probability that a random card is a heart is 1/4.

Excluding the big and small kings, * * * has 52 pieces, and the hearts 13 pieces.

The probability of encountering is: 13÷52= 1/4.

Put this outside, and the probability that the next one is the heart is 12/5 1.

At this time, the total number is: 52- 1=5 1.

There are 13- 1= 12 hearts.

The probability of encountering is:12 ÷ 51=12/51.
