order
A game is played by throwing a fair dice until either a six is obtained or four throws have been made. The number of sixes obtained in the game is denoted by Y. Find EY (or the mean of the frequencies ~ Expectation in statistics)
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.
but it also has to do with how many dice r being played
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
wat type of math is this?
It's statistics 1 for A-levels
yup, and measures of spread.
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.
