A boxcar contains six complex electronic systems. Two of the six are to be randomly selected thorough testing and then classified as defective or not defective. a) If two of the six systems are actually defective, find the probability that at least one of the two systems tested will be defective. Find the probability that both are defective. b) If four of the six systems are actually defective, find the probabilities indicated in part a)

15 units use socratic

step-by-step explanation: 15 units

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

really your just stupid if you don't know this
