a cloth sack contains 25 red beads, 75 green beads, and 50 blue beads. If a single bead is drawn at random, what is the probability that it will be green?

Answer:
1/2 or 50%
Step-by-step explanation:
25 red beads, 75 green beads, and 50 blue beads = 150 beads
P(green) = number of green beads / total
= 75/150
= 1/2 or 50%
