Answer:

<em>P=37.5%</em>

Step-by-step explanation:

<u>Frequentist Probability</u>

The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.

The equation to calculate the probability is:

\displaystyle P=\frac{f}{n}

Where f is the number of favorable cases and n is the total cases.

John has in a cup of his desk:

6 pencils

3 blue+5 black+2 red pens=10 pens

Picking one of the utensils from the cup can be done in 16 different ways. That is the total number of cases n=16

The outcome of taking a pencil can be done in 6 ways. That is the number of favorable cases. f=6.

The probability is:

\displaystyle P=\frac{6}{16}

Simplifying:

\displaystyle P=\frac{3}{8}

Or expressed as a percentage:

P=3/8*100%

P=37.5%

Answer:

A) 5  3/10

B) 785 3/20

Step-by-step explanation:

Hope this helps <3

you find a common denominator and then simplify all fractions to that common denominator. then, you add them up!

2 1/5 + 3 1/10

5 can fit into 10 twice so it becomes...

2 2/10 + 3 1/10 which equals

<u>5 3/10</u>

472 2/5 + 312 3/4

5 times 4 is 20

472 8/20 + 312 15/20

there is a remainder of 3 for the fractions so you put it over 20.

<u>785 3/20</u>
