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?

6 blue + 14 green = 20 total on average, he would expect about 6/20 = 3/10 of the beads to be blue multiply 3/10 by the total number of beads in the bag
