Answer:
0.0025 = 0.25% probability that both are defective
Step-by-step explanation:
For each item, there are only two possible outcomes. Either they are defective, or they are not. Items are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
5 percent of these are defective.
This means that 
If two items are randomly selected as they come off the production line, what is the probability that both are defective
This is P(X = 2) when n = 2. So


0.0025 = 0.25% probability that both are defective
Answer:
62 days
Step-by-step explanation:
Given that she reads 9 pages everyday before falling asleep. Then, on day one, she would read 9m pages.
On day 2, she would read another 9 pages, making 18 pages after 2 days. If she will finish the book in x days then
x = 550/9
=61 1/9 days
Converting the 1/9 into a day then, she will finish the book in 62 days, reading just a page on the 62nd day.
