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 Red or Jacks card.

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

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

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
