To find the probability you must multiply the probability of rolling doubles by itself 3 times.
to roll a double of any number you have to have the same number on a six-sided die that can be represented as 1/6 times 1/6 = 1/36 chance per roll
there is a 1 in 46656 chance in rolling doubles 3 times in a row.

<h3><u>Part A</u></h3>
factor the common term 'y' and '-4'
collect into groups
middle term split
factor the common term '3x' and '-2'
collect into groups
simplify the following
You made a mistake with the probability , which should be
in the last expression, so to be clear I will state the expression again.
So we want to solve the following:
Conditioned on this event, show that the probability that her paper is in drawer , is given by:
(1) and
(2)
so we can say:
is the event that you search drawer
and find nothing,
is the event that you search drawer
and find the paper,
is the event that the paper is in drawer
this gives us:
Solution to Part (1):
if , then
,
this means that
as needed so part one is solved.
Solution to Part(2):
so we have now that if =
, we get that:
remember that:
this implies that:
so we just need to combine the above relations to get:
as needed so part two is solved.
