Probability

[Guest]

I would like to know three percentages of outcome, I am not versed in maths, thanks.

I am on a pool table looking at three balls, five balls and seven balls.
My success rate of potting each ball is 80%, what would the success rate be of potting 3 balls in succession of 80% and 5 balls in succession and 7 balls in succession, every ball has a 80% success rate
I am a pool coach for beginners and the answers would assist that, thank you.

If the probability of pocketing any one ball is 80%, the probability of pocketing 3 in a row is [tex](0.8)^3= 0.512[/tex]. For 5 balls in a row the probability is [tex](0.3)^5= 0.32768[/tex], and for 7 balls, it is [tex](0.8)^7= 0.2097152[/tex].
