If one card is drawn from a deck find the probability of get

If one card is drawn from a deck, find the probability of getting these results. Enter your answers as fractions or as decimals rounded to 3 decimal places.

Solution

there are 4 suits in the deck - hearts, spades, diamond and clubs. out of these 4 suits 2 are black colored (spades and clubs) while the other two are red (hearts and diamond).

so the number of red card = 2 x 13 = 26

so probability of a red card = 26 / 52 = 0.5
