If a probability graph is 'negatively skewed', is the x coordinate the turning point the probability of sucess?
If so,  is that the case if its positvely skewed aswell? ;)

Naa its not that graph.
This one comes up quite rarely but is part of the course though.
Check your text for 'positively skewed' and negatively skewed probability graphs.

positvely is where p<0.5
negatively is where p>0.5

oh ok in that case isnt the probability of success on the y -axis, and the corresponding x -value on the x-axis
