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 .2. a what is the probability that the third hole drilled is the first to yield a productive well

0.128 is the probability that the third hole drilled is the first to yield a productive well.

Step-by-step explanation:

We are given the following information in the question:

The probability that he is successful on a given trial is 0.2    

p = 0.2

q = 1 - p = 0.8

We define the geometric probability as:

For this we have x = 3, putting the values we have:

0.128 is the probability that the third hole drilled is the first to yield a productive well.

answer: 0.26

i used the calculator on google

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
