The integers are -3, -1 and +1.
_________________________
Step-by-step explanation:
Let the first integer is X
=> the other two consecutive odd integers are X+2 and X+4
Now we have given that their sum is 7 less than 4 times the largest number
Thus the first integer is -3
the second is (-3+2) = -1
and the third integer is (-3+4) = +1

Answer:
Events E and F are independent.
Step-by-step explanation:
E = {multiple of 3} = {3, 6, 9, 12}
P(E) = 4/12
F = {even number} = {2, 4, 6, 8. 10, 12}
P(F) = 6/12
E and F = {even and multiple of 3} = {6, 12}
P(E∩F) = 2/12
In order for two events to be independent the following relationship must be true:
Testing this property:
The relationship holds true, thus events E and F are independent.
