Question

jake has a bag of 50 beads, of which some are red and the remaining are yellow. jake randomly pulls out a bead from the bag, records the color, and replaces it in the bag. jake has already recorded 6 red and 9 yellow beads. based on the result, what is most likely the number of red beads in the bag? 10 20 30 40

Answer 1

Let the number of red beads be x, then the number of yellow beads is 50 - x.
Then, 6/9 = x/(50 - x)
9x = 6(50 - x) = 300 - 6x
15x = 300
x = 300/15 = 20

Therefore, we expect 20 red beads in the bag.
