The probability that a dessert sold at a certain café contains strawberries is 26%. The probability that a dessert contains both strawberries and whipped topping is 18%. Find the probability that a randomly chosen strawberry dessert contains whipped topping. Round to the nearest tenth of a percent.

P (Strawberry) = 26% = 0.26

P (Whipped) = x

P (Strawberry and Whipped) = P (Strawberry). P (Whipped) = 18% = 0.18

∴ P (Whipped) = P (Strawberry and Whipped) / P (Strawberry) = 0.18/0.26 = 0.6923 = 69.23%

To nearest tenth,

P (whipped topping) = 69.2%

∴ Probability that a randomly selected desert contains whipped topping is 69.2%.
