Answer and Step-by-step explanation:

It depends on the numbers that are inputted for a and b.

If the numbers that are inputted for both a and b are rational, then a + b would be rational.

If the numbers that are inputted for both a and b are irrational, then a + b would be irrational.

If one of the variables is rational and the other is irrational, then a + b would be irrational.

Answer:

The given statement is false.

Step-by-step explanation:

We are given the following in the question:

$f(x) = \text{In } x$

The given statement is

$f(x - 2) = f(x) - f(2), x > 2$

Putting the values on the right side of the given statement

$f(x-2)\\=\text{ln }(x-2) \neq \text{ln }x - \text{ln }2$

Thus, the given statement is false.

This can be explained with the help of an example:

For x = 3

$f(x-2) = f(3-2) = f(1)\\=\text{ln }1 = 0\\f(x)-f(2)\\=\text{ln }3-\text{ln }2 \\=0.4054$

Step-by-step explanation:

There are 13 types of cards (A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K), out of which 3 (J, Q, K) are face cards. This means that the probability for the first half is 3/13. There are 4 suites (Club, Spade, Hearts, and Diamonds). This means the probability of attaining a club is 1/4. 3/13 * 1/4 = 3/52
