1. PROBABILITY 3

2. Probabilities can be calculated using information given on a Venn diagram.

3. In a survey, 25 students are asked if they like banana ice-cream (B) and if they like chocolate ice-cream (C). The Venn diagram shows the results. C B 689 2 a A student is chosen at random. Find the probability that they like both banana and chocolate ice-cream. Probability = b A student who likes chocolate ice-cream is chosen at random. Find the probability that they also like banana ice-cream Probability = c Two students are chosen at random. Find the probability that they both like banana ice-cream

4. In a survey, 25 students are asked if they like banana ice-cream (B) and if they like chocolate ice-cream (C). The Venn diagram shows the results. C B 689 2 Probability = d Two students are chosen at random. Find the probability that only one of the students likes banana ice-cream first student likes banana and the second student does not first student does not like banana and the second student does
