25-B- Financial Expectation (1 Viewer)

[deeznuts]

Hmm i know this has been asked alot, but please bear with me

i didnt read question properly - stupid i know

in the first question i got the correct answer a 0.8 but i did this

o.8= Financial expectation
0.8 x 60 = Financial Expectation of all games
$48 = Total financial expectation


2nd part i got 2/3 but again times by 60


2/3 or 0.67 = Drop of 13 cents
2/3 x 60 = total financial expectation
$40 = Total financial exepectation

Therefore it does change because it has dropped.... etc



Both these questions are worth 2 each, i wasnt sure wat id get because i did correct working and got the right answer, but took it further..


What do u guys think?

Thanks

yeah i reckon u will get 1 for ii) and iii) instead of 2. you showed working, just got the wrong answer. good luck with the reults and rest of exams

80 cents and 67 cents were the right answers BUT you might get 2 coz u showed FINAL financial expectation...who knows...its over...u can forget abt it

people have to realise a financial expectation is expected from ONE game, not 60. even though she plays 60 times, it asks for "the game", not what is "her" financial expectation.

so if i did 0.88 and 0.67 respectively with correct working out i get the 2 marks?!

 

[danieljarvis]

it was 0.80 and 0.67... 13c difference, and ud have to say no shes wrong...

im not sure what marks u would get sry

 

[deeznuts]

yea i realise that now jsut made stupid mistake,

i assumed that the game had 60 rolls

but i know realise that she played the game 60 times

stupid i know, was just curious considering i got the right answers for both questions, but took it a little further
