Anumber 'a' is to be chosen at random from the set {1, 2, 3, 4, 5, 6}. a number 'b' is then to be chosen at random from the remaining five numbers.
what is the probability that a/b will be an integer?

answer:

- if x is to be chosen at random from the set {1, 2, 3, 4} and y is to be chosen at the set {5, 6, 7}, what is the probability that xy will be even? (a) 1/6 (b) 1/3 (c) 1/2 total number of possible xy values is 4*3=12 (x can take any 4 values from what have i included in the probability to make it 1/6 bigger than the right answer?

step-by-step explanation:

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
