An automatic machine inserts mixed vegetables into a plastic bag. past experience revealed that some packages were underweight and some were overweight, but most of them had satisfactory weight. weight % of total underweight 2.5 satisfactory 90.0 overweight 7.5 what is the probability of selecting three packages that are satisfactory?

0.729

Step-by-step explanation:

Given : The weight percentage of satisfactory packages = 90%

i.e. The probability of selecting a satisfactory package = 0.90

Since selecting each package is an independent event.

Thus, the probability of selecting three packages that are satisfactory will be:_

Hence, the probability of selecting three packages that are satisfactory = 0.729

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%
