If A and B are independent events, which equation must be true?
P(B/A) = P(A)
P(B/A) = P(B)
P(B/A) = P(A) * PIB)
P(BIA) = P(A) + P(B)

step-by-step explanation:

i took the test: )

the answer is y = 11.54

hope this : )

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).
