Question

Jake has a bag of 50 beads, some of which are blue and the remaining are green. Jake randomly pulls out a bead from the bag, records the color, and replaces it in the bag. Jake has already recorded 6 blue and 14 green beads. Based on these results, what is most likely the number of blue beads in the bag?

15
20
30
35

Answer 1

15

Explanation:

Answer 2

15

Explanation:

Jake has pulled 6+14 beads , or 20 beads from the bag.

6 of them have been blue

The experimental probability is

P ( blue) = blue/total = 6/20 = 3/10

To determine the number of 50 beads that are blue in the bag, take our experimental probability times the number of beads

3/10 * 50 = 15

The best estimate is 15 of the beads are blue
