PROBABILITY 1

A card is picked at random from a pack of playing cards. Find the probability that it is a red card.

Solution

Total playing card is normally 52. Half of them(26) are red.

 n(E) = 26, n(S) = 52, P(E) = ?

P(E) = n(E)

           n(S)

P(E) = 26

           52

  P(E) = 1

              2

 Probability that it is a red card is ½
