Let V be the event that a vanilla cupcake was bought, C be the event that a chocolate cupcake was bought, R be the event that a red velvet cupcake was bought, and O be the event that a orange cupcake was bought.
“n=12+10+8+7=37”
“I) P(R)={8 over 37}”
“II) P(Vcup C)={12+10over 37}={22over 37}”
“III) P(Vcup Ocup C)={{12+7+10}over 37}={29over 37}”
“IV) P(bar{O})=1-P(O)=1-{7over 37}={30over 37}”
