Warm-upDay of Ch. 6 Test Explain when to use binompdf(n, p, k) versus geompdf (p, k). Both graphs above display p = 0.1. Explain why the graphs are different.
# 4 from Practice Test A game of chance involves rolling fair die. If the die shows a 1, you win $4; if it shows a 2, you win $0.50; and if it shows any other number, you win nothing. Not winning anything means you lost $1 for playing the game. If the cost to play the game is $1, what are the player’s expected winnings? (A)Lose $0.08 (B) Lose $0.25 (C) Win $0.08 (D) Win $0.25 (E) Win $0.75 Include the loss of $1 in the winnings OR Calculate chance of 3(1/6) - 0.5(1/6) – 1 (4/6) = -$0.25 winning then subtract $1 4(1/6) + 0.5(1/6) + 0 (4/6) = 0.75 -$1 + 0.75 (return) = -$0.25
