This is very easy to solve once you understanding writing equations. In this case, we could do n+6=100 because we know that the number of songs he has now (n) plus 6 will equal 100. Below is a solution for this equation.

n+6=100
   -6     -6
n=94

After solving our equation, we know that Kirk has 94 songs.

In a game, you toss a fair coin and a fair six-sided die. If you toss a heads on the coin and roll either a 3 or a 6 on the die,

Using probabilities, it is found that the expected profit of one round of this game is of $0.

A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.

  • One of the two sides of the coin are heads.
  • 2 of the 6 sides of the dice are 3 or 6.

Hence, since the coin and the dice are independent, the <em>probability </em>of winning is:

p = \frac{1}{2} \times \frac{2}{6} = \frac{1}{6}

The expected value is the <u>sum of each outcome multiplied by its respective probability</u>.

In this problem:

  • \frac{1}{6} probability of earning $30.
  • \frac{5}{6} probability of losing $6.

Then:

E(X) = 30\frac{1}{6} - 6\frac{5}{6} = 5 - 5 = 0

The expected profit of one round of this game is of $0.

Given:

12cm to 2.5mm

To find:

The simplified for of given statement.

Solution:

We know that,

1 cm = 10 mm

12 cm =120mm

We have,

12cm to 2.5mm

It can be written as

\dfrac{12\ cm}{2.5\ mm}=\dfrac{120\ mm}{2.5 mm}

\dfrac{12\ cm}{2.5\ mm}=\dfrac{120}{2.5}

\dfrac{12\ cm}{2.5\ mm}=48

Therefore, the value of 12 cm to 2.5 mm is 48 or 48:1.
