A box contains 15 transistors, 5 of which are defective. If 5 are selected at random, find the probability of the statements below. a. All are defective
b. None are defective

The answer must be in a fraction

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
