A consumer report counted 727272 low-quality, 112112112 medium-quality, and 711711711 high-quality computers based on a random sample. The report went on to say that all computers, regardless of quality, are packaged identically and sold at the same price.

Use the observed frequencies to create a probability model for the quality of the next computer purchased.

Frequency

Low-quality 727272 / 824551095

Medium-quality 112112112 / 824551095

High-quality 711711711 / 824551095

Step-by-step explanation:

A probability model is a table of all possible outcomes and the frequency with which we expect them to occur. The probability of any quality computer is number of that quality computers / total number.
