Answer: 0.1

Step-by-step explanation:

Since the number cube is rolled twice , the sample space is 36 , that is the total number of possible outcomes is 36.

The success criteria for a sum of 9 appearing are:

3/6 , 4/5 , 5/4 , 6/3

Therefore , the probability of a sum of 9 appearing= $\frac{n(sum of 9)}{Total sample space}$

= 4/36

= 1/9

=0.111111...

Unsure of what you're asking.

If you have an algebraic expression in front of you and see a number there, you could label it as "known" or "a known quantity." Another word that comes to mind is "constant."

Expand in logarithmic expression

olchik [2.2K]

$ln( \frac{m^{5}}{n^{2}})^{3} =3ln( \frac{m^{5}}{n^{2}})= 3(ln({m^{5})-ln({n^{2}))=3(5ln(m)-2ln(n) = 15*ln(m)-6*ln(n)

$

The answer is 15*ln(m)-6*ln(n)
