a number cube has its sides numbered as 1,2,4,6,7 and 5.if a cube is thrown once, what is the probability of rolling of an odd number?

Dear Student,

Please find below the solution to the asked query:

We know formula for probability :

Probability P ( E )  = Total number of desired events n ( E )Total number of events n ( S )

Here , A cube has its sides numbered as 1 , 2 , 4 , 6 , 7 and 5

So,

n ( S ) = 6  (  As we have six sides of cube )

And

Total number of desired events = 5 and  7  (  As these are the odd numbers in given numbers )

n ( E ) = 2

Therefore ,

Probability of  getting  an odd number = 26 = 13                                   ( Ans )

Hope this information will clear your doubts about Data handling .
