Your Question:
John is about to roll a six-sided, fair number cube 60 times. He wants to predict how many times the cube will land on an even number. He makes a prediction of 20 times. Is it a good prediction? What would your prediction be based on theoretical probability?
My answer:
each dice has these 6 numbers
1,2,3,4,5,6
the even out of all of the numbers are
2,4,6
The others are odd (obviously)
1,3,5
So 1/2 are odd.
1/2 of 60 is the number of times it would get even numbers,
1/2 of 60=1/2 times 60=30
My prediction was 30!

Answer:
2/405
Step-by-step explanation:
Simplify the following:
(-2)/9×((-1)/3×1/3)/5
(-1)/3×1/3 = (-1)/(3×3):
(-2)/9×((-1)/(3×3))/5
(-1)/(3×3)×1/5 = (-1)/(3×3×5):
(-2)/9×(-1)/(3×3×5)
(-2)/9×(-1)/(3×3×5) = (-2 (-1))/(3×3×5×9):
(-2 (-1))/(3×3×5×9)
3×3 = 9:
(-2 (-1))/(9×5×9)
9×5 = 45:
(-2 (-1))/(45×9)
45×9 = 405:
(-2 (-1))/405
-2 (-1) = 2:
Answer: 2/405
