Probability Simulations The word simulate means to imitate or model. A probability simulation is the use of some method to model or represent a real experiment or situation. • Simulations can involve: • Calculators and computers to generate random numbers • Dice, coins, spinners, coloured counters etc • Random number tables
Example 1 For families of 5 children, what is the probability that the girls outnumber the boys. Devise a simulation of this situation and use it to determine the probability is more than, less than, or equal to 0.5. • Solution: • Tossing a coin: head = boy, tail = girl • Rolling a die: 1 – 3 = boy, 4 – 6 = girl • Random numbers using calculator: 0 – 4 = boy, 5 – 9 = girl • Deck of cards: red = boy, black = girl
