Answer:
6
Step-by-step explanation:
The 4 and 12 are multiplied together which creates 48 (4*12). Then you divide the 48 by 8 (48/8) wich equals 6.
First you should add all the number of rolls.
The number of rolls is 80.
Subtract 80 from 400.
The answer is 320.
Add 320 to the number of rolls of 3.
The answer to the question is 322.
I am sorry if I am wrong.
-244 is an integer, rational and real number
I believe this is the way to solve it.
22 - 2 = 20
20 is 90.9% of 22
So the probability of choosing a student with a sibling at random should be 90.9% (or you can round up to 91%)
I hope this helps :)
