The operation indicated, A - B, is a subtraction of sets.

The subtraction of set B from set A means that you have to remove the elements of B that are on A; i.e. A - B = {15, 35, 55}

25, 45 and 65 (which are in the set B) were removed from the set A to form the set A - B

Answer:

199.5in^3

Step-by-step explanation:

To do this we first need to find the area of the triangle to do that we can do 3.5*2=7

(since there are two triangles we can do it like this to make it easy)

then we can multiply it like so

7*28.5=199.5

Hope this helps :)

Answer:

  1. The probability that the locker code begins with a prime number is 40%.
  2. The probability that the last digit of the locker code is an odd number is 40%

Step-by-step explanation:

  1. Prime numbers are the numbers that only divide with 1 or itself. So in this case it is 5 and 7.

The possible combinations are

1*4*3 (with 5) +  1*4*3(with 7) = 24

Total combinations are 5*4*3=60

(24/60)*100 = 40 %

     2. Odd numbers are those which don't divide with 2. So in this case it is 6 and 8.

The possible combinations are

1*4*3 (with 6) +  1*4*3(with 8) = 24

Total combinations are 5*4*3=60

(24/60)*100 = 40 %
