You can put this solution on YOUR website! .
Calculate the total jellybeans.
For each question, calculate the number of favorable jellybeans.
To answer each question, take the ratio of favorable to the total.
All your questions are of the complexity level of "how many is 2 + 2 ?",
So even a person unfamiliar with the formal definition of the probability,
can answer all these questions based on his or her common sense.
