Question 10.2 · May/June 2025 · Paper 1 · National (DBE) · 6 marks

10.2 A game at a fun park requires a player to roll a six-sided dice and pick a card from a deck of 52 cards. A player wins if an odd number appears on the uppermost face of the dice and the player also draws a picture card from the deck. A deck of cards has 4 suites (hearts, diamonds, spades and clubs). There are 4 picture cards (king, queen, jack and ace) in every suite. A player pays R10 to play a game and in an hour, 260 people can each play one game. If the owner wants to make a 70% profit per hour, calculate the maximum amount that the owner must pay out to each winner.(6)
