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.

Answer:
m∠A = 30°
m∠B = 80°
m∠C = 70°
Step-by-step explanation:
By applying cosine rule in the given triangle,
b² = a² + c² - 2ac[cos(∠B)]
From the given triangle,
a = 14 m
b = 28 m
c = 24 m
(28)² = (14)² + (24)² - 2(14)(24)cos(B)
784 = 196 + 576 - 672cos(∠B)
cos(∠B) = 0.1786
∠B =
∠B = 79.71°
∠B = 80°
By applying sine rule in the given triangle,
sinA = 0.491958
A = 29.47°
A ≈ 30°
By applying triangle sum theorem,
m∠A + m∠B + m∠C = 180°
30° + 80° + m∠C = 180°
m∠C = 70°
