Question

Gerald buys a bag of 7500 assorted beads online a random sample of 150 beads contains 17 red beads. Predict the number of assorted beads that Gerald bought.

Answer 1

850 red beads

Explanation:

One way to do this problem is to set a proportion.

red beads/red beads = total beads/total beads

Let x = the no. of red beads in the bag

x/17 = 7500/150

x = 17(7500)/150 = 850 red beads
