Q4)
from a set of 6 cards numbered 1,2,3,4,5,6, a card is chosen and then a second selection is mader
from among the remaining five cards. draw a tree diagram of the event space and find the probability
that an even digit will be selected:
i) the first time
ii) the second time
iii) both time
iv) neither is even

boxplot e is the answer

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.
