30 % possibility

[jmrag]

Can you provide me with a code where

...........

if(....)
{....}

where if has 30% possibility to be executed?

Another way to look at 30% is 30/100 ('thirty out of a hundred'). Thus, if you generate a uniformly distributed random number x in [0,100], then you have a 30% chance that x <= 30.

For the actual implementation, check this webpage:
