Aconsumer report counted 72 low quality, 112 medium quality, and 711 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

Step-by-step explanation:

A probability is the number of desired outcomes desired by the number of total outcomes.

I am going to say that we have these following events

L is the event that a computer is low quality.

There are 72+112+711 = 895 computers. Of those, 72 are low quality. So

M is the event that a computer is medium quality.

Of the 895 computers, 112 of them are medium quality. So

H is the event that a computer is medium quality.

Of the 895 computers, 711 of them are medium quality. So

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
