1/4 = 5/20
2/5 = 8/20
8/20 + 5/20 = 13/20 has been spent
The answer to this is $32
Assuming there are 6 sides on the dice, then there are 36 different outcomes
The 36 comes from the result of 6*6 = 36
If you want, you can draw out a table that has 6 rows and 6 columns. There will be 36 cells which are the results of adding any two combinations of the two dice.
Use the law of cosines.
a2+b2−2abcosC=c2
Find the measure of angle C. It is the opposite side of c.
c2−a2−b2−2ab=cosC
cosC=13.62−22.52−182−2(22.5)(18)≈0.797
C=cos−10.797=0.649 rad=37.19∘
angle B:
a2+c2−2accosB=b2
cosB=b2−a2−c2−2ac
B=cos−1b2−a2−c2−2ac=cos−1182−22.52−13.62−2(22.5)(13.6)≈0.927 rad=53.13∘
angle A:
b2+c2−2bccosA=a2
A=89.68∘
