Measure based on measure

[Anonymous]

Hi community,

Im trying to get some sort of probabilty for a room for a given hour that it is occupied.
I have a table contain all the meetings in certain rooms, each room has 2 chambers., start and end date for each meeting.
I want to look at the odds that when someone chooses a room, it is currently occupied for that hour, and then take a column average across the given date interval for all the rooms on that hour. Instead of the column total, the average probability should be calculated.

Hopefully my screenshot will make things a bit more clear.

First matrix shows the number of meetings between the specified date and is derived using the following measure:

Occupancy v1 = 

VAR MinDateTime =
    MIN ( 'Dim_Date'[Date] ) + MIN ( 'Dim_Time'[Time] )
VAR MaxDateTime =
    MAX ( 'Dim_Date'[Date] ) + MAX ( 'Dim_Time'[Time End] )

    VAR Counter = 
    DAY(MaxDateTime)

RETURN

    CALCULATE ( 
        DISTINCTCOUNT ( 'MRoom'[CDR_ID]); 
        'MRoom'[Start_datetime] < MaxDateTime;
        'MRoom'[End_datetime] >= MinDateTime
    )

The second matrix is incorrect as it should give me the probability which Im after but again, incorrect.

Value 101 was a test, probabilities can't be higher than 100 of course*

Can a measure be created to calculated these probabilities based on the values of another measure??
Im quite new to DAX and PB and not sure about context etc.

Thanks for any info or tips on how to model my model!

Cheers.
