The expected value formula is given by;
[tex]\text{Expected value= }\sum ^{}_{}xPr(x)[/tex]Where x is the possible winning and Pr(x) is the probability of that same win.
Going through the table; we can compute the expected value of the winnings as;
[tex]\text{Expected value=1(0.12)+4(0.2)}+6(0.38)+8(0.2)+10(0.1)=5.8[/tex]Therefore, the expected value of winning is $5.8
