[INA-pweh]

very useful n thank u so much for the vid

[TheZadzzz]

you are officially my maths teacher :)

could they put a question where the arcs are of different sizes and we have to work out the probability of that of one? it doesnt seem that hard etc but just wondering. Also for mechanics could they not set it up with this and different areas with some not given where we have to work this out and then a given force on the wheel, with friction R on the spin and we have to work out where it will land? or we are told how many rotations it had and where it landed and we have to work out what the initial force is? would they also potentially include wind resistance?

or does A level not get that hard?

how do you find mean and variance form this table?

[ayamsakata]

hey.. do you have a complete sort of uhm.. playlist of all the videos you got involving this subject.. because i really am having a hard time on deciding which is to watch next.. tnx

I am confused at how the second example with the "roll the die" gives values of -50p and 10p. Surely winnings only refers to the money won from the game, which is still 0p and 60p? I understand that the profit would be -50 and 10p, but aren't profit and winnings different things? 

[dimuthudaundasekara]

good work... this time i'll pass the exam well ... thanks ... god must protect you..

[pujaverma]

In example 2 how is the probability of -50 is 3/6 and from the winnings, 50 is deducted so the probability of -50 should be 6/6 because it is used in all the 3 winnings.

what about P(X=0) for the third question?

What If the problem was "create a discreet probability distribution of 50 students who answered a survey regarding what type of residence they lived in. 33 people answered they lived in a house, while 17 answered they lived in an apartment"

Question:
1. How am I supposed to find the mean when there is only 2 choices and they aren't numerical?

Your writting on the vedio are obsqure the discussion
