Abox contains 12 transistors, 3 of which are defective. if 3 are selected at random, find the probability that none are defective.

explain how you get the answer, i know it involves a #c#

3 divided by 12 equals 0.25
So we change 0.25 to a fraction which is 1/4
The probability is 1/4

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
