Answer:
Step-by-step explanation:
The standard form refers to the way of writing large numbers in a smaller expression using power of 10, this is also called scientific notation.
To write this number in standard form, we have to the decimal point to the position between the 5 and the 4, and all spaces jumped represent the exponent of the 10 power, as follows
Therefore, the standard form would be

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%
