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

All right triangles have two legs, which may or may not be congruent. The legs of a right triangle meet at a right angle. The other side of the triangle (that does not form any part of the right angle), is called the hypotenuse of the right triangle. This side of the right triangle will always be the longest of all three sides. The angles of a right triangle that are not the right angle must be acute angles.
