From the past studies it is know that 60% of the students at HIGH read the Age newspaper. There was a recent article in the Age on the rise in living costs in Melbourne. If the class size is 20,
A) what is the probability that none of the students read the article?
B) what is the probability that at least 75% of the students read the article?
Do I use the bionomial probability?
I am hopeless at math. Any hints or input would be muchly appreciated.
