Its B just took the test the answer is B
The name of period that has the digits 913 is hundreds.<span>
Because Period is considered to a group of places of the digits.</span>
In this case, the given number is 913 and it is the group of hundred because 900 is the highest number it contains.
We can also write 913 as
913 = 900 + 10 + 3
It means,
<span>9 hundreds + 10 tens + 3 ones</span>
Rolling an even number would be 1/2 possibility while flipping tails would be 1/2 possibility hence the answer is 1/4
