The answer is C because multiplication comes first
Answer:
The answer is ![\frac{1}{256}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B256%7D)
Step-by-step explanation:
If we assume that people cannot taste a difference between bottled water, then the probability of identifying tap water is 0.5
Thus, P(identify tap water)=0.5
The probability that at least 8 of the 9 people identify the tap water correctly is the sum of the probabilities
- 8 of 9 people identified correctly or
- 9 of 9 people identified correctly
Since P(identify tap water)=0.5 each probabilities are the same and equal to
=![\frac{1}{512}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B512%7D)
So we have
= ![\frac{1}{256}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B256%7D)
The value of the (RIC) will increase from 4 to 5.75,that is,44%
