GCSE Secondary Maths Age 13-17 - Probability & Statistics: Probability - Explained

The video tutorial explains a charity game designed by Carl using a fair 10-sided dice. Players win if the dice lands on a multiple of 4. The tutorial covers calculating the probability of winning, which is 2 out of 10, and simplifying it to 1/5 or 20%. It also estimates the funds raised for charity if the game is played 100 times, with each play costing 30 pence and a prize of 1 pound per win. The expected profit is calculated by subtracting the prize money from the total collected amount. The tutorial concludes with a summary of the probability and fundraising concepts.
