SOLUTION
From the question, we want to find the probability of selecting a slip of paper with the letter t on it, then selecting the letter r, with replacement.
This means the probability of selecting t and r.
That is
There are 12 letters (total outcomes). And there are 2r and 2t.
So probability becomes
Hence the answer is
<em><u>Question:</u></em>
Consider the relation {(−5, 8), (4, −2), (4, 1), (3, 0)} . What integer is in the domain?
A 8
B -2
C -5
D -1
<em><u>Answer:</u></em>
Option C
The domain is -5, 4, 4, 3
<em><u>Solution:</u></em>
Given relation is:
<em><u>Let us understand about domain and range</u></em>
Domain refers to the set of possible input values
Range is the set of possible output values
Thus the input values in given relation are:
(x, y) = (-5, 8) , (4, -2) , (4, 1) , (3, 0)
The input values are values of "x"
Input values = -5, 4, 4, 3
Thus the domain of given relation are -5, 4, 4, 3
Thus option C is correct
