Jerry Harrison · Answer 1

1. Total number of marbles=10 red marbles+80 green marbles+110 orange marbles=200 marbles

2. Let's call "V" the event that consists that he selects a green marble from the bag. Then:

P (x) = 80/200

P (x) = 0.4

3. This problem can be represented by a binomial distribution, where:

P=0.4

q=1-P=0.6

n=50

4. The expect value in a binomial function is written as below:

E (x) = nxP

E (x) = 50x0.4

E (x) = 20

The answer is: He can expect 20 zucchini.
