Using the probability concept, it is found that there is a

a) 0.2 = 20% probability that 3 is obtained.

b) 0.3333 = 33.33% probability that 6 is obtained.

c) 0.6667 = 66.67% probability of a number greater than 3.

d) 0.6667 = 66.67% probability of an even number.

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

Item a:

There are 5 numbers greater than 1, one of which is 3, hence:

$p = \frac{1}{5} = 0.2$

0.2 = 20% probability that 3 is obtained.

Item b:

There are 3 numbers greater than 3, one of which is 6, hence:

$p = \frac{1}{3} = 0.3333$

0.3333 = 33.33% probability that 6 is obtained.

Item c:

There are 3 even numbers, two of which are greater than 3, hence:

$p = \frac{2}{3} = 0.6667$

0.6667 = 66.67% probability of a number greater than 3.

Item d:

There are 3 numbers greater than 3, two of which are even, hence:

$p = \frac{2}{3} = 0.6667$

0.6667 = 66.67% probability of an even number.

Check the picture below.

$\textit{area of a circular ring}\\\\ A=\pi (R^2-r^2)~~ \begin{cases} r=\stackrel{smaller}{radius}\\ R=\stackrel{larger}{radius}\\[-0.5em] \hrulefill\\ r=2\\ R=3 \end{cases}\implies \begin{array}{llll} A=\pi (3^2-2^2)\implies A=5\pi \\\\\\ A\approx 15.71 \end{array}$
