A box contains green marbles and blue marbles. Yosef shakes the
box and randomly draws a marble. He records the color in the table
at the right (refer to picture) and places the marble back into the box. Yosef repeats the
process 50 times.
a. Develop a complete probability model for choosing a marble.
b. Based on the experimental probability, about how many times will
Yosef draw a green marble if he draws a total of 75 marbles?
