    45 times

    Step-by-step explanation:

    Firstly, we find the probability of drawing a green bead.

    The total number of beads is 8 + 6 + 6 = 20 beads

    Now the number of green beads is 6

    The probability of drawing a green bead in one trial would thus be 6/20 = 3/10

    Now we want to do this 150 times. A reasonable estimate for the number of times a green bead would be drawn is 3/10 * 150 = 45 times
