A bag contains 4 red balls and 1 blue ball. One ball is drawn at random. Which statement is correct?
ARed and blue are equally likely because there are two colours.
BBlue is more likely because it is a different colour.
CRed is more likely because there are more red balls than blue balls.
DRed is impossible because only one ball is drawn.
Answer & Solution
Correct answer: C. Red is more likely because there are more red balls than blue balls.
The outcomes 'red' and 'blue' are not equally likely here because the bag has 4 red balls and only 1 blue ball. Since red has more favourable cases, drawing a red ball is more likely.
