It is noted that 8% of Kaplan students are left handed. If twenty (20) students are randomly selected,
calculate the
i. probability that none of them are left-handed, (2 marks)
ii. probability that at most 2 are left-handed, (3 marks)
iii. mean and standard deviation for the number of left-handed students
(3 marks)
(b) Do you agree that ¡°if two events are mutually exclusive then these two events will be independent¡±?
Why?
Provide one business-related example each, with explanation, for mutually exclusive and
independent events.
