2. An insurance company surveyed 150 drivers. The survey showed that 115 drivers had no accident for at least one year, 46 had at least one traffic violation this past year, and 21 drivers surveyed had at least one violation and an accident this past year. Answer the following questions. Drawing a Venn diagram may be help.
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.
Can you answer question 2?? Please and thank you.
Given data:
The total numbers of drivers are n(U)=150.
The number of drivers that had no accidents is n(S)=115.
The numbers of drivers that had at least one traffic violation are n(V)=46.
The numbers of drivers that have one violation and accident in the past year are n(A)=21.
(a)
The expression for the probability that the selected driver had no accident and no violation in the past year is,
Substitute the given values in the above expression.
Thus, the probability that the selected driver had no accident and no violation in the past year is 0.6.
