3) an oil prospector will drill a succession of holes in a given area to find a productive well. the probability that he is successful on a given trial is 0.2. what is the probability that the third hole drilled is the first to yield a productive well?

0.128

Step-by-step explanation:

The geometric probability of getting success on nth trial is given by :-

Given : The probability that he is successful on a given trial.

Then , the probability that the third hole drilled is the first to yield a productive well is given by :-

Hence, the probability that the third hole drilled is the first to yield a productive well = 0.128

tube or goog would be a great resource to with that question

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
