Question

One card is drawn from a pack of 52 cards, each of
the 52 cards being equally likely to be drawn. Find
the probability that the card is red and a king.​

Answer 1

There are 26 red cards (including 2 kings) and there are 2 more kings. So, the number of favourable outcomes = 26+2=28. ∴ P(getting a red card or a king) =P(E1)=2852=713.

Answer 2

number of red cards = 26

number of red king = 2

probability of red king card =

$\frac{pe \: of \: red \: king }{pe \: of \: total \: cards}$

$\frac{2}{52} = \frac{1}{26}$
