is the probability that he selects a prime
number and then a 1?
1,2,3,4,5

Answer 1

Answer: 3/20 or 0.15

Explanation:

Answer 2

A 3/20 in saying this; About a 3 out of 5 chance

Explanation:

Prime number hmmm

5

Then a 1

Watch this

5-1 is 4

4-1 is 3

5*3= 15

15+5=20

3/20= 0.15

Take out the decimal and it is the same thing you got when you did 3*5

ALSO

1-5= -4

-4+5=1

1*5=5

5*4=20

1*4/2=2

5-2=3

SAME RESULT

3/20= 0.15

Take out the decimal and it is the same thing you got when you did 3*5
