Probability of rolling a sum of 9 or a sum that is even from two number cubes is
11/18
Explanation:
When a dice is rolled there are different ways in which
9. can be obtained, which are (3,6) or (4,5) or (5,4) or (6,3). 4 options. As in all there are
6⋅6=36 options, probability is 4/36 or 1/9.
For getting an even number as sum, we can have (1,1) or (1.3) or (1,5) or (2,2) or (2,4) or (2,6) or (3,1) or (3,3) or (3,5) or (4,2) or (4,4) or (4,6) or (5,1) or (5,3) or (5,5) or (6,2) or (6,4) or (6,6) 18 options, probability is 18/36 or 1/2.
Note that the two events (getting 9 or even sum) are mutually exclusive, the probabilities can be just added i.e. combined probability is
1/9+1/2=2+9/18i.e. 11/18
It's not a function because the x value repeated but wasn't accompanied by the same y value . there is (-2,2) and (-2,14) but if they had the same y value like (-2,2) and (-2,2) or (-2,14) and (-2,14) the table would represent a function. If you still dont understand I'll be more than happy to elaborate :)
Answer:
<em>coefficient</em><em> </em><em> </em><em>because</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em>not</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>so</em><em> </em><em>they</em><em> </em><em>can</em><em> </em><em>not</em><em> </em><em>be</em><em> </em><em>constant</em><em> </em><em>because</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>not</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>in</em><em> </em><em>every</em><em> </em><em>week</em>
