Well 4 out of the 5 are odd. So the probability the first digit is odd is (4/5) since that digit is no longer available, then the probability the second digit is odd is (3/4), then for the third (2/3), then the forth (1/2).
So to find the first four being odd is (4/5)*(3/4)*(2/3)*(1/2) = 24/120 = .20
Answer:
<em>The smaller integer is -3 and the greater integer is -2</em>
Step-by-step explanation:
<u>Equations</u>
Let's call
x = the smaller integer
x + 1 = greater consecutive integer
The relationship between them is that twice the smaller is four less than the greater:
2x = x + 1 - 4
Subtracting x:
x = 1 - 4
Operating:
x = -3
x + 1 = -2
The smaller integer is -3 and the greater integer is -2
