Answer:

probability: 4/6 = ~66.67%

simplified: 2/3

Step-by-step explanation:

Prime numbers are numbers that cannot be factored into smaller natural numbers (whole numbers).

In a ordinary cube, there are 6 sides, numbered 1 - 6. Find the factors of each number:

1: 1

2: 1 ,2

3: 1 , 3

4: 1 , 2 , 4

5: 1 , 5

6: 1 , 2 , 3 , 6

If there is any number with only 1 and the number itself, then it is a prime number. In this case, it will be 1, 2, 3, 5, or 4 sides in all.

4/6 is your probability of rolling a prime number for a fair dice.

Most likely, you will need to simplify. Divide 2 from both numerator & denominator:

(4/6)/(2/2) = 2/3

2/3 is your simplified answer.

There are 1420 students enrolled at Senn. If 60% of these students walk to school, how many students are walking to school?
pychu [463]

Answer:

852 students walking to school

Step-by-step explanation:

Lets start with a simple example so you can get it

if 60% of 100 students walk to school that means

60 students walk to school... right??

so lets simplify it more that means you have multiplied 100 (students) by 60%

or \frac{60}{100}  (note: you can say that 60% is equal to \frac{60}{100} )

so the problem told 60% of 1420 students walk to school that means we should

do this:     1420*\frac{60}{100} = 852
