Question

A box contains 100 colored chips; some are violet and some are red. wilson chooses a chip at random, records the color, and places it back in the bag. Milton has recorded 9 violet chips and 16 red chips. Using these results, what is the predicted number of violet chips in the box

Answer 1

36

Explanation:

Wilson records 9 violet chips and 16 red ones.

So from a sample of 25 chips, 9 are violet.

So violet probability out of 25 = 9/25.

If we make a proportion we find how many violet chips out of 100 = 36

9/25 = ?/ 100

?= 36
