"Driver Fatalities The following data represent the number of drivers involved in a fatal crash in 2016 in various light and weather conditions.

"Putting It Together: Success Sequence

Explain what is meant by a subjective probability. List some examples of subjective probabilities.

Playing Five-Card Stud

In the game of five-card stud, each player is dealt one card face down and four cards face up. After two cards are dealt (one down, one up), players bet, and betting continues after each additional card is dealt. Suppose three cards have been dealt to each of five players at the table.
