A local bank reports that 80% of its customers maintain a checking account, 60% of them have a savings account, and 50% of them have both. If a customer is chosen at random,
what is the probability the customer has either a checking or a savings account? What is
the probability the customer has neither a checking nor a savings account?

(Hope this helps can I pls have brainlist (crown)☺️)

Step-by-step explanation:

In pic

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
