A"true or false" test has five questions.
if you guess the answers, what is the
probability that you will get exactly two
correct?

5/16.

Step-by-step explanation:

The probability of getting a correct answer on one question is 1/2 and the probability of getting it wrong is  1 - 1/2 = 1/2.

The probability of the first 2 being correct and the next 3 wrong = (1/2)^5 = 1/32.

There are  10  possible combinations of this ( first wrong the 2nd and third right and last  2 wrong,  etc).

So the  required probability is 10 * 1 /32

= 10/32

= 5/16.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
