Answer:

39/40

Step-by-step explanation:

Since 39 out of 40 marbles are green, the probability of randomly choosing green is 39/40.

However, the probability becomes 100% when you look into the bag and choose a green marble. (Unless you are blind or unable to distinguish blue from green, in which case the probability remains 39/40.)
