Option B
When you roll two number cubes, the odds in simplest form against getting two numbers greater than 3 is 1 : 4
<h3><u>Solution:</u></h3>The probability of an event is given as:
Given that,
Tow number cubes are rolled
<em><u>To find: Probability of getting two numbers greater than 3</u></em>
On a number cube there are 6 numbers {1, 2, 3, 4, 5, 6} Out of which 3 numbers are greater than 3 {4, 5, 6}
So, total number of possible outcomes = 6
Favourable outcomes = number greater than 3 = 3
When you roll one number cube, probability of getting number greater than 3:
<em><u>When you roll two number cubes, probabilty is given as:</u></em>
In ratio form we can write as 1 : 4
Option B is correct

For a better understanding of the solution provided here please go through the diagram in the file that has been attached.
As can be clearly seen from the question and the graph, the area is bounded by a straight line which passes through the origin, the y axis and the horizontal line
.
As we can see from the graph, this is a right triangle. To find the point of intersection of the horizontal line y=6 and the line , we will have to equate the two as:
Therefore,
Thus,
Hence the point of intersection is (12,6) which is depicted on the graph too.
As this is a case of a simple right triangle, the area of the bounded region will thus be:
Let the base be the y=6 line whose length is 12 and let height be the y axis whose length is 6, thus, the area will be:
squared units.
