Answer: 72 beads

Explanation:

From the question, we have the information that Johnathan picked colored beads from a jar 50 times and replaced the bead each time. Jonathan picked a red bead 12 times, yellow bead 14 times, and a blue bead 24 times.

Out of 50 picks, the following beads were picked:

Red = 12

Yellow = 14

Blue = 24

Total = 50

Fraction of blue bead = 24/50 × 100

= 48%

The blue beads that Johnathan will pick out of 150 beads will be:

= 48% of 150

= 48/100 × 150

= 0.48 × 150

= 72 blue beads

Jonathan will pick 72 blue beads out of 150 beads.
