What is probability?
Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Deck of cards contains,
spade=13, heart=13, diamonds=13, clubs= 13
In which clubs and spades are black and hearts and diamonds are red.
Total (Black suited card with a heart) =26+13= 39
P( heart or a black-suited card)=39/52
=3/4.
Hence, probability of heart or a black-suited card is 3/4
