Suppose that X is a binomial random variable with n = 10 and p = 0.25. Find P 2).
Write only a number as your answer. Round to 4 decimal places (for example
0.1849). Do not write as a percentage.

0.2816

Step-by-step explanation:

X ~ B(10, 0.25) q = 0.75

10C2 × 0.25² × 0.75⁸

= 0.2815675735

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
