**Solution:**

We know that,

Total number of cards = 52

So, the total number of outcomes = 52

There are 13 cards of each type. The cards of heart and diamond are red in colour. Spade and diamond are black. Hence, there are 26 red cards and 26 black cards.

(i) Number of black cards in a deck = 26

The number of favourable outcomes for the event of drawing a black card = 26

Then, probability of drawing a black card = 26/52 = ½

(ii) Number of red cards in a deck = 26

Therefore, number of non-red(black) cards = 52 – 26 = 26

The number of favourable outcomes for the event of not drawing a red card = 26

Then, probability of not drawing a red card = 26/52 = ½
