Expected value=(0*27+100*1+50*1+30*1)/30=$6.00
"fair" would be the expected value...but no games of chance charge a "fair" value. :)
ABC is equal to MNP. This is because you have to look at the order of the angles/sides. ABC goes from A with 3 congruency arcs to B with 1 congruency arc. For MNP, start with M that has 3 congruency arcs then go to the next angle with one congruency arc which is N
3/10
2/5 x 3/4 = 3/10 and that is in simplest form
That’s pretty hard be confident you can do it♀️
