how is my set up wrong???

the table looks good. Is your book showing something else?

no idea :P

Now just sum the final column to get your expected gain/loss.

HI!!

you want a simple way to do it?

yea I am adding it up but it is not right

buy all 100 tickets at $10 each
how much did you spend?

1000?

yes of course
how much money do you get back?

if that is not clear, i can explain, it is a very simple calculation

oh yea how would I calculate that?

one $480 prize
two $75 prizes
5 $20 prizes

\[480+2\times 75+5\times 20=?\]

oh right right it is 730

you spent $1000 you get back $730
how much money did you lose?

270$

exactly
averaged over the 100 tickets that is a loss of \(270\div 100=2.7\)

There are 4 tickets where you win $20, not 5 tickets

ahh so there are !

$-1.90??

that means you only get $710 back for a total loss of $290

$-2.90

right

thanks so much cool way to solve it
but do you possibly know the mistake on my chart

let me look

ok thnx

ok i see why

same with all the other numbers

i.e. when you win $75 it is a net gain of $65 and when you win $20 it is a net gain of $10

do it using your method but with the new numbers and you will get it
