A basket of beads contains 8 red beans , 6 yellow beads, and 6 greens . A bead will be drawn from the basket and replaced 150 times. What is the reasonable prediction for the number of times a green bead is drawn

8 + 6 + 6 = 20
6/20 or 3/10
3/10 x 150 = 45
Or you could do 6 x 150 to get 900, and then divide by 20, the denominator, to get 45 as well :)

Explanation:

green is 6 out of a total of ( 8+6+6 = 20 ) beads

so 6/20 ths of the time it should be a green bead

6/20 * 150 = 45 times should be green
