Answer: 0.14155776
Step-by-step explanation:
Given : The proportion of workers employed by the university belong to the workers' union=0.96
Let x be a binomial variable that represents that worker belongs to the workers' union.
Sample size : n= 4
[Binomial probability formula : P(X=x)=^nC_x(p)^x(1-p)^{n-x}]
Hence, the probability that exactly 3 of the workers interviewed are union members
Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know:</h3>all we need to care about the middle condition which is
<h3>the new test score is 15 points more than the original score</h3>given that
original score is x
New score is y
if you pay attention to the given condition
we can find it same as linear equation
therefore
according to the question
the equation is
<h2>y=x+15</h2>
