Question

Two cubical dice are thrown simultaneously, the probability of getting total at least '9' is a) 5/36 b) 8/36 c) 10/18 d) 1/9​

Answer 1

Answer : the ans is b 5/36

Step-by-step explanation:  

Probability shows the relationship between two variables in the form of ratio, percentage or proportion where there the chances of occurrence of one variable is expressed in terms of the other variable which is usually sample space.  

The sample space for the given problem is 6x6 = 36  

Let the required event be E ( getting a total of at least '9')  

n(E) = 10

Therefore, P( getting a total of at least '9') = n(E)/S  

                                                                  =10/36

                                                                  = 5/18
