Question

A research company conducted a survey to determine the attendance of registered voters in a series of campaign rallies conducted by three aspiring candidates, Abigail, Benson and Charles, in a small but crucial ward in Nairobi. Among the 1500 registered voters interviewed:

• 650 attended Abigail’s rally
• 550 attended Benson’s rally
• 780 attended Charles’ rally
• 250 attended both Abigail and Benson’s rallies
• 350 attended both Abigail and Charles’ rallies
• 280 attended both Benson and Charles’ rallies
• 130 attended rallies of all three candidates
• The survey revealed voter apathy noting that quite a sizable percentage of those polled did not attend any of the rallies.
