Which of the following describes a simple event?
a. spinning a spinner and drawing a card from a deck of cards
b. tossing a coin
c. drawing 3 cards from a deck of cards
d. tossing 4 coins

Answer – B (Tossing a coin)
 A simple event is an event where only one experiment happens at a time (such as tossing a coin), and the event has only one outcome. When two events are occurring simultaneously(such as spinning a spinner and drawing a card from a deck of cards, drawing 3 cards from a deck of cards or tossing 4 coins), then it is no longer a simple event; it is a complex event.
