After running this program several times i noticed that my y value is somewhere between 60-80 every single time.

I thought because 70^2 is 4900 that i would end up with my y value ending up around 1 each run through, but actually its about a 1 in 70 chance of the dice equaling each other. 

So why is it that rolling 2 70 sided dice and having the results equal each other is not a 1/4900 chance, but rather a 1/70 chance? Heres the program...

```
x=0
y=0

while x < 4900

  random = rand(70)
  random2 = rand(70)

  puts " "
  puts random
  puts random2

  if random == random2
    puts "the numbers matched"
    y+=1
  end

  x+=1

if x == 4900
  puts " "
  puts y
end
end

```
