    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.
