Homework Statement
This looks like a very simple question but I just can't seem to wrap my brain around it:
Homework Equations
Baye's theorem, etc.
The Attempt at a Solution
For part (a)
To calculate this probability I need to know the sample space of the programmers right? This is the main thing I'm having trouble with.
I was thinking I just need to add up how many know Java, C, and Assembly (30 + 25 + 16) for the sample space and divide that by the number of people that know Java.
The amount of people that know Java would be 30 (Java) + 15 (Java and C) + 6 (Java and Assembly) + 5 (Java and C and Assembly).
So would the probability be 56/107? I'm really not sure about it though because I feel like I'm double-counting somewhere
