Hi class,

The binomial distribution allows us to face circumstances where the results belong to two relevant categories.

Based on the above, I will propose the following exercise, which I hope you can resolve satisfactorily.

The probability of success of a medicine for allergies is 75%, calculate the probability that when consumed by 10 patients:

1. None suffer some type of allergy.

2. They all suffer some type of allergy.

3. 5 of them suffer some type of allergy.
