Find the odds of getting a 1 or a 4 and then subtract your result from 1 (probability of the complement of getting a 1 or a 4).
A fair die has six possible outcomes when tossed: {1, 2, 3, 4, 5, 6}. The probability of getting a 1 or a 4 on one toss is 1/6 + 1/6, or 2/6, or 1/3.
Thus, the odds of NOT getting a 1 or a 4 is 1 - 1/3, or 2/3.
Answer:
Answer is in the attached image.
Answer:
8
Step-by-step explanation:
6(2.3)-(3.5+2.3)
13.8-5.8
=8
The elementary row operation that will reduce the x–element in row 2 to 0 in this matrix is -2R1 + R2
<h3>How to determine the
elementary row operation?</h3>
The complete question is added as an attachment
The matrix is given as:
1 1 1 12
2 1 0 14
2 0 3 19
Rewrite as:
x y z
1 1 1 12
2 1 0 14
2 0 3 19
So, the x-element of the second row is
x = 2
When the first row is multiplied by negative 2 and added to the second row, the x-element of the second row is reduced to 0
This is represented as;
-2R1 + R2
i.e.
-2(1 1 1 12)
+ 2 1 0 14
---------------------------
0 -1 -2 -10
Hence, the elementary row operation that will reduce the x–element in row 2 to 0 in this matrix is -2R1 + R2
