Inputs are the first number output is the second. So youre outputs are 2, -1, -1, and 3. so i would say b
Answer: No. Quincy should have used the trend line to find the corresponding x value when y=80.
Wait i will tell you soon dont worry, im out now sorryy ^.^
2×3=6
6×1=6
12÷2=6
Sorry if these don't help.
We will use binomial
distribution in this problem.
<span>The solution would be like
this for this specific problem:
</span><span>P(default) = p = 4% = 0.04 </span><span>
<span>q = 1-p = 1-0.04 = 0.96 </span>
n = 5</span>
<span>P(r) = nCr*q^(n-r)*p^r </span>
<span>Required probability =
P(r=2) = 5C2*0.96^3*0.04^2 </span>
= 0.0142 OR 1.42%
<span>The probability that at most
two customers in the sample will default on their payments is 1.42%.</span>
