Answer:
The probability that it will take a week for it three wet weather on 3 separate days is 0.06166 and its standard deviation is 0.9447
Explanation:
Probability of wet weather = 0.15
Probability of not being a wet weather = 1-0.15
We are supposed to find probability that it will take a week for it three wet weather on 3 separate days
Total number of days in a week = 7
We will use binomial over here
n = 7
p =probability of failure = 0.15
q = probability of success=1-0.15
r=3
Formula :
Standard deviation =
Standard deviation =
Standard deviation =0.9447
Hence The probability that it will take a week for it three wet weather on 3 separate days is 0.06166 and its standard deviation is 0.9447
I would say C. Hope this helps!
Answer:
Option B
Explanation:
According to the given question, we are asked to state the rock layer that must be porous and have enough permeability for fluid to move through the layer.
As a result of this, we can see that we are assuming that fracking has not been used with the oil and gas well and this rock layer would need to be permeable so that fluids can move through it to other areas.
Therefore, the correct answer is option B
