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
