X, Y and Z are three mutually exclusive events. P(X) = 0.4, P(Y) = 0.3 and P(
XU Z) = 0.6.
Find:
() P(XUY)
(i) P(Z)
(ii) The probability that none of X, Y or Z
happens

y=mx+b

step-by-step explanation:

m slope, b y-intercept

the answer

b. they are parallel and will never intersect.

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).
