what if i will buy 5 tickets?

[@MathandStatsHelp]

Your expected loss would just be 5 times the expected value.

@@MathandStatsHelp Oh, i see. Thank you so much! :)

Can we find a positive expected gain??

[@MathandStatsHelp]

Yes, you would just need to change the signs around for the x values. A loss to the person would be considered a gain to the company, and a gain to the person would be considered a loss to the company.

Is expected value and expected gain are same or different.

[@MathandStatsHelp]

They are pretty much the same thing. Both are calculated the same way.

@@MathandStatsHelpDo I have to consider net profit only for every outcome while calculating expected value.
