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%

Answer:
Length of B is 7.4833
Step-by-step explanation:
The vector sum of A and B vectors in 2D is
And its magnitude is:
Where
Using the properties of the sum of two angles in the sin and cosine:
Sustituying in the magnitud of the sum
Solving for B
Sustituying the value of the magnitud of A
