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 16 blue and 4 green beads. based on these results, what is most likely the number of blue beads in the bag? 10 20 30 40

I would think that is was 30 because 16 + 4 + 30 = 50. But I also would think that it is 40 because 16/20 = 3/4 = 0.8. And 0.8 * 50 = 40. I mean, if someone could give some insight, that would be great.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
