Two numbers are randomly selected from integers 1 through 9. What is the probability that only one of the integers is odd given that the sum of the two numbers is odd?1/4
1
40/81
5/40
Answers
Another one where there's a danger of overthinking it !
The sum of ANY two integers is odd only if one is even and one is odd.
If they're both odd OR both even, then their sum is even.
So if their sum is odd, then one is odd and the other is even.
The probability is ' 1 ' (100%) .

Answer with Step-by-step explanation:
Let the ones digit of the number be y
and tens digit of the number be x.
The tens digit is two less than the units digit.
i.e. x=y-2
The value of the number exceeds twice the sum of its digits by 19.
i.e. 10x+y=2(x+y)+19
10(y-2)+y=2(y-2+y)+19
10y-20+y=2(2y-2)+19
11y-20=4y-4+19
11y-4y=20-4+19
7y=35
dividing both sides by 7, we get
y=5
Putting value of y in x=y-2, we get
x=3
10x+y=10×3+5
=35
Hence, the two digit number is:
35

When Sarah added the fertilizer and there was a noticeable difference, we can say that:
- B. This is an example of causation but not correlation.
What is Causation?
Causation occurs when an effect is noticed because of a traceable item. The traceable item, in this case, is the fertilizer.
So when the fertilizer was added and a change in color was noticed, we can deduce that the difference was because of the fertilizer.
Therefore, option B is correct.
