Question

A bag contains a total of 300 red chips and white chips. Suppose a student chooses a chip out of the bag, records the color, and then places the chip back in the bag. The student has recorded 29 red chips and 21 white chips. Using this result, what is the BEST prediction for the number of red chips in the bag?

Answer 1

Answer: 174 red chips

Step-by-step explanation:

A bag contains a total of 300 red chips and white chips. A student chooses a chip out of the bag, then records the color, and places the chip back in the bag. By doing this, the student recorded 29 red chips and 21 white chips.

To predict the number of red chips in the bag using this method goes thus:

Number of red chips picked= 29

Number of white chips picked= 21

Total number of chips= 29+21 = 50

So, the student picked 29/50. Out of 300 chips, number of reds that will be picked will be:

= 29/50 × 300

= 29 × 6

= 174 red chips
