The Venn probabilities for this problem are given as follows:
a. 0.9 = 90%.
b. 0.1 = 10%.
<h3>What is a Venn probability?</h3>
In a Venn probability, two non-independent events are related with each other, as are their probabilities.
The "or probability" is given by:
For this problem, the events are given as follows:
- Event A: Checking account.
- Event B: Savings account.
From the text, the probabilities are given as follows:
From item a, the or probability is given as follows:
There is a 0.9 = 90% probability the customer has either a checking or a savings account.
For item b, <u>none is the opposite of either</u>, hence there is a 1 - 0.9 = 0.1 = 10% probability the customer does not have either a checking or a savings account.

<h3>How to simplify a product of rational numbers</h3>
Herein we are in front of a product of three <em>rational</em> numbers, that is, numbers of the form m / n, where m, n are integers and n ≠ 0. We need to apply definition and theorems from algebra to simplify a given number, whose procedure is shown in detail:
(2 3 / 4) · (1 1 / 8) · 32 Given
(2 + 3 / 4) · (1 + 1 / 8) · 32 Conversion from mixed numbers into rational numbers
(11 / 4) · (9 / 8) · 32 Addition of fractions with different denominators
(99 / 32) · 32 Mutiplication of fractions

∗ The question says "bikes" which refers to more than 1, and there are 3 people.
∗ It costs $18 a day to rent a bike.
∗ They are renting for 5 days.
∗ Let x represent the number of days.
∗ Let b represent the number of bikes.
∗ Let y represent the total cost.
∗ (b • 18)x = y
∗ (3 • 18)5 = y
∗ 54 • 5 = 270
∗ There are 3 people splitting the cost, so you divide 270 by 3 to get 90.
∗ Each person pays $90
