Answer:

Step-by-step explanation:
Let A and B events. We have defined the probabilities for some events:

Where A' represent the complement for the event A
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
So for this case we can solve for P(A) like this:

And now we can find
using the total probability rul given by:

And if we replace the values given we got:

And that would be the final answer.
N = number of given days
p = photos on phone
p - (20n) =
Answer:
480,000
Step-by-step explanation:
1,000,000 x 0.48 = 480,000
480,000 = 48% of 1 million
