a better way to randomize an event?

high. im new to programming, so please bare with my noobishness. ive been working on a text based RPG game in the past few days, and in a lot of the program i needed to randomize the chance of an event happening (Ex. when you kill an enemy, the chances of him dropping loot). well, i found that i was doing it so much for so many different things, (ex not only chances of enemy dropping loot, but also chances of many other things such as what spell the enemy casts or if the enemy casts a spell at all, etc.) anyway, i made my own function to do this now. basically it works like this bool random_bool() { bool chance; int random = rand() % 100; //make a random number 1-100 if (random >=50) //if its more then 50, return true chance = true; } else // if its less then 50, return false { chance = false; } return chance; } now, in my program when i want to randomize an event (say for the event of an enemy dropping loot when he dies), i do drop_loot = random_bool(); if (drop_loot == true) { drop loot code; } basically the fucntion just randomizes a boolean value the way rand() randomizes a number. it seems to be working pretty well so far, but im just wondering if what im doing is completely wrong, or if theres a different, or a built in way to do this. thanks for any input ps-(i realize that the function only works if you want a 50/50 chance of something happening, im going to change it so you can send it the chances through a parameter instead of it being hard coded) p s s - is it truly a 50/50 chance? or am i wrong about that?

I've heard that you shouldn't use rand() for yes / no, since the least significant digits aren't very random.

For boolean true or false, you only need one bit. If the lower bits don't vary very much, or are not very well distributed, then take a higher bit..

Rand() & (1 << n)
