This is a discrete distribution

Situations that can be modeled with the binomial distribution must have these 4 properties: Only two possible outcomes Probability of success is fixed for all trials There are a fixed number of trials Trials are independent of each other

In a school it is noted that 30% of all students are left handed. In a group of eight students what is the probability that a) Exactly five of them are left handed b) Only one student is left handed

From the last situation… a) Over half the students are left handed b) No more than 4 students are left handed

Now the pages 144 – 149 are able to be done. But in class we will use the textbook…
