I have to calculate the probability of 1 success in 3 trials.
The probability of one success in one trial is 0,27.
I used Bernoulli pattern to calculate it and that what I got below. I assume I can't use it properly or I don't understand something.
The probability of success in two trials is 0,39
The probability of success in three trials is 0,43
The probability of success in ten trials is 0,16 !!!????
The probability of 2 successes in ten trials is 0,26 ??? how that's possible?
I don't understand, if 3 trials gives 0,43, so 10 trials should be about 1 or above (in my opinion). Thank you in advance for explanation.
