The two triangles are similar.
40/x = 32/4
x = 5
Answer:
see screenshot
general formula is
r² = (x - x-center)² + (y - y-center)²
in every die thrown 100 times a six occurs 32 times
so the probability of obtaining a die after 100 throws = 
X is a integer that is less than 10 because integers are negative and positive numbers. Therefore, there can be infinite negative numbers.
