Hello, I need some help with one math problem:
"There are TWO events, one of these events has probability 0,84. (nothing is said about other event ) What probability is to have 4 of 6 such events occured."
As I imagine these events should happen in pairs [0,84, ???], [0,84, ???] and [0,84, ???].
6 events, 3 probabilities unknown.
