The exponential distribution is:
where
The probability we want is how likely will a dvd player last more than 8 years, given it has already lasted 5 years
To find this, you use conditional probability.
where A is P(x>8) and B is P(x>5)
To find these probabilities, integrate over the distribution:
Sub into conditional probability formula:
Final Answer: Given a dvd player is more than 5 years old, the probability that it will last another 3 more years is about 54.9%
An expression equivalent is the
Step-by-step explanation:
you start with 90 then 180 then270 then 360
Remember: √-1=i
√-16=(√16)(√-1)=(i)(√16)=i(4)=4i
1-4i
