Answer:

0.5

Explanation:

A deck of cards has 52 cards. Out of which 26 are red and 26 are black. The black cards are further divided into two suits.

So,

total sample space = n(S) = 52

Let A be the event that the drawn card is a black card

Then,

n(A) = 26

So, the probability of A will be:


P(A) = (n(A))/(n(S))\\ = (26)/(52)\\ =(1)/(2)\\ =0.5

Hence the theoretical property of drawing a black card is 0.5 ..
