Question

If the probability of success during a single event of a geometric experiment is 0.16, what is the probability of success by the 8th event? Round your answer to the nearest tenth of a percent.

Answer 1

i think general formula is \[(1-p)^{k-1}p\]

Answer 2

but that might be the probability of success for the first time on the kth trial

Answer 3

"by the 8th event" might be \[1-(1-9)^8\]

Answer 4

i meant \[1-(1-p)^8\]

Answer 5

in your case it would be \[1-.84^8\]
