Determine the Probability
From a pack of playing cards what is the probability of;
(i) Picking either a 'Diamond' or a 'Heart' → mutually exclusive
(ii) Picking either a 'Flower' or an 'Ace' → indecent events
Solutions
(i) P(Diamond or Heart)
= P (Diamond) + P(Heart)
= (13/52) + (13/52) = 26/52
= 0.5
(ii) P(Flower or Ace)
= P(Flower) + P(Ace) - P(Flower and Ace)
= (13/52) + (4/52) - (1/52)
= 4/52 = 0.31
Note: the formula used in case of independent events is different to the one of mutually exclusive.
