④ Strawberry 45 people bought one or two scoops of ice cream. 5 • 20 bought strawberry. Chocolate 15 15 10 • 10 didn’t buy chocolate or strawberry. • 30 bought chocolate. How many people bought both flavours? If I pick a person at random, what is… P(strawberry) = P(only chocolate) = P(only one flavour) = 15 20 + 30 = 50 but there is meant to be 35 people inside the circles. 15 must have bought both!
