Hello Everybody.
I'm not good enough about probability and my problem is that I can't sum up bernoulli probability.
Let's assume that we're throwing a dice.
1 step. Probability of succes in first try is 1/6.
2 step. Now we're choosing 2 walls, so probability of succes is 2/6.
3 step. Now 3 walls, so probability of succes in third is 3/6.
Can I just sum it up? then I will receive probability equal 1. But it isn't true. If I bet wall with 1 in first trial, on second I bet wall with 1,2. In third trial I bet wall with 1,2,3. The probability is 1 but it is very possible that during the 3 throws I will not receive any of these walls.
