Vedic Maths trick to find Probability solutions

One card is drawn randomly from 52 deck of cards.What is the probability that the card drawn is either Black or 2 card.

Lets take total event = 52
n(S) = 52

Now, Total number of Black card including Black color '2' is 26.
and Two Red color '2'

Total card will be 26 + 2 = 28
n(E) = 28

Now we will put the value in the given formula

P(E) = n(E)/n(S)

P(E) = 28/52

P(E)=7/13
