Robert has 20 pieces of candy in a bag: 4 mint sticks, 6 jelly treats, and 10 fruit tart chews. if he eats one piece every 4 minutes, what is the probability his first two pieces will both be mint sticks?

a. 1/25
b. 9/380
c. 3/95
d. 2/5

Step-by-step explanation:

20 pieces of candy

4 mint sticks

6 Jelly treats

10 fruit

Total: 40

4 / 40 = 0.1

0.1 x 100 = 10%

or

2 / 20

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.
