The effectiveness of a vaccine for a certain disease is about 45%. This means that 45% of the vaccinated person will not get the disease when exposed. Assume that each person’s response to the disease is independent of another person’s response. 1) Find the probability that less than FIVE (5) persons will not get the disease if 12 people are exposed. 2) Find the probability that more than SIX (6) persons will not get the disease if 10 people are exposed. 3) Suppose a new vaccine has been introduced for the disease. The experimental study shows that the probability of NONE out of 12 people exposed will not get the disease is 0.05. Find the probability of effectiveness of the new vaccine
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

1) Find the
exposed.
2) Find the probability that more than SIX (6) persons will not get the disease if 10 people are exposed.
3) Suppose a new vaccine has been introduced for the disease. The experimental study shows that
the probability of NONE out of 12 people exposed will not get the disease is 0.05. Find the probability of effectiveness of the new vaccine
