R = red cars
J = cars manufactured in Japan
32 of the people she asked watch sports regularly.
An incomplete Venn diagram for her data is shown below.
a) Complete the Venn diagram.
b) Work out P(W∪P) for someone picked at random.
c) Work out the probability that someone picked at random watches sports regularly but not play sports regularly
All 50 people like at least one of the drinks
19 people like all three drinks.
16 people like tea and coffee but do not like milk.
