Probability: Balls in a Box
The presentation presents a box containing m white balls and n black balls. Students are asked to explore the probability that if two balls are chosen consecutively, without replacement, the two balls are the same colour. A spreadsheet simulating the situation is provided to enable students to experiment. The experiment is repeated a number of times, each time recording whether the balls chosen were the same colour. The probability of both balls being the same colour is calculated. The presentation concludes by showing a connection with triangle numbers which can be tested using the spreadsheet simulation.
