from league store i bough four silver/gold mods, with the probability 50/50. all turned out silver…

the probability to pull 4 silver in a row is (0,5)^4 which is 1/16. so 1 person out of 16 should get all 4 mods silver… which is possible…

i had problems with game odds before. when leveling adrenaline rushes of 5* i had a 33% chance of succes and 66% the oposite using 10x same trait characters. sometimes i didnt had ar lvl up succes for 9 times in a row using 10 same trait characters (90x 2* characters). the probability of this happening is (0,66)^9 which is close to 1/42, so i should be 1 in 42 person to not succed lvl up of ar this way. the problem is i had it numerous times…

so the question is are the game odds broken or am i this mega unlucky?
