When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive. When you multiply two integers with different signs, the result is always negative.

First of factor the common term 3a
3a(2a+7)/ 3a^2----------->   $\frac{3a(2a+7)}{3a^{2} }$
cancel out the 3
a(2a+7)/a^2--------------->   $\frac{a(2a+7)}{ a^{2} }$
simplify
2a+7/a---------------------->   $\frac{2a+7}{a}$

If you guess the answers at random, what is the probability of getting at least two correct answers on a five-question true-or-f

mamaluj [8]

Since each question only has two outcome, which is yes/no. A five question true/false quiz is consist of five true/false factors.

True/false can be simulated as 1/2, or half the change of being correct.

Now if you put 1/2 to it’s fifth power, or (1/2)^5, since there are five questions.

The chances of getting ALL FIVE questions right is 1/32, now if you want to have two questions correct, which is 2/5 of the probability, then we would only need to raise the power to 3, since you we’re considering the other three would be definitely wrong

(1/2)^3 = 1/8
In result, the probability of getting 2 out of 5 questions correct is 1/8
