Answer:
The probability of 2 or more errors is 0.018.
Step-by-step explanation:
Let <em>X</em> = number of typographical errors on a page of a certain magazine.
The expected number of errors is, <em>λ</em> = 0.2.
The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 0.2.
The probability mass function of <em>X </em>is:
Compute the probability of 2 or more errors as follows:
P (X ≥ 2) = 1 - P (X < 2)
= 1 - P (X = 0) - P (X = 1)
Thus, the probability of 2 or more errors is 0.018.
Answer:
46 boxes
Step-by-step explanation:
- First 10 boxes can be bought for
- Next 10 boxes can be bought for
<em>So for a total of </em><em>20 boxes, </em><em>the cost is </em>
<u>We have remaining </u>
Each additional box costs 3.5, so for 91 dollars, we can get:
boxes
So, total boxes can be bought for $221.00
