Response: a) 0.9980, b) 0.0013, c) 0.0020, d) 0.00000026, e) 0.0318
Detailed explanation:
In Problem 8-4, the computer time-sharing system experiences teleport inquiries at an average rate of 0.1 per millisecond. We are tasked with determining the probabilities of the inquiries over a specific period of 50 milliseconds:
Given that

Applying the Poisson process, we find that
(a) at most 12
probability= 
(b) exactly 13
probability=

(c) more than 12
probability=

(d) exactly 20
probability=

(e) within the range of 10 to 15, inclusive
probability=
Thus, a) 0.9980, b) 0.0013, c) 0.0020, d) 0.00000026, e) 0.0318
Answer: You would need 40 bushels of seed to plant 30 acres of wheat.
Step-by-step explanation:
<pTypically, 1 1/3 bushels of seed are necessary to cultivate 1 acre of wheat. In improper fraction form, 1 1/3 bushels becomes 4/3 bushels.
Let x denote the bushels of seed required for 30 acres. Thus, we have
4/3 bushels = 1 acre
x = 30 acres
Cross multiplying gives us
x × 1 = 4/3 × 30
x = 40 bushels of seed
