ey=1/2 for 6 and 1/3 for 4?

Nope. This is under Varience and standard deviation and Expectation... so there are a lot more steps involved.. It's not easy. So if anyone knows how to solve this... I'll be very greatful. Thanks for trying though :) But It's not as straightforward as that.

Only one set of dice, rolled numerous amounts of times... It also has to do with Geographic & binomial distribution... All 4 things combined... not easy

wouldnt it be division to find out how many times thrown to the actual number

Nope.. It'll be to find the distribution of Y (the hard part) and then to get the expectation, which is much easier.
