Question

A basket of beads contains eight red beads six yellow beads and six green beads. A bead will be drawn from the basket and replaced 150 times. What is a reasonable prediction for the number of times a green bead is drawn?

Answer 1

45 times

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
