Probability of an event being active
Hi,
This is my first time here and I hope that I am asking for help in the correct place.
This is the problem I need to figure out:

This is the given set of data:
Over a 1000 second interval
Time of event P = 12 seconds
Chance of event P occuring = 11.25%
Frequency of F = 2.8325 seconds

every 2.8325 seconds event F occurs. 11.25% of the time that F occurs, event P will occur. event P lasts for 12 seconds.

The problem:
On average, how many times will event P have occurred?
What is the average amount of time that event P will be active?

Thank you for your time and help!

Edit: sorry! i made a typo and wrote K in the problem instead of P :(

I am not really interested in the final answer, but rather the method on how to figure out a problem like this in the future. I am sure there has been a formula made on solving something like this, its just what and where it is, is stumping me.
