प्रश्न
An ordinary deck of cards contains 52 cards divided into four suits. The red suits are diamonds and hearts and black suits are clubs and spades. The cards J, Q, and K are called face cards. Suppose we pick one card from the deck at random. What is the event that the chosen card is a black face card?
उत्तर
Let E be the event that a black face card is chosen.
The outcomes in E are Jack, Queen, King or spades or clubs.
Symbolically:
E = {J, Q, K, of spades and clubs}
or
E = {J♣, Q♣, K♣, J♠, Q♠, K♠}
