= x
change x to (x) and y back to x, thus
(x) =

Answer:
3/5 of a minute
Step-by-step explanation:
1/3 of a page in 1/5 of a minute = 2/3 of a page in 2/5 of a minute = 3/3 (or 1) page in 3/5 of a minute.
A) 26.7%
B) 40%
The probability of A is given by 4/6(2/5), since this is done without replacement; there are 4 blue marbles out of 6. When the first one is gone, there are 2 red out of 5 remaining.
The probability of B is given by 4/6(3/5), since this is done without replacement; there are 4 blue marbles out of 6. When the first one is gone, there are 2 blue out of 5 remaining.
