Answer:
C
Step-by-step explanation:
The explicit formula for a geometric sequence is
= a
where a is the first term and r the common ratio
From the recursive formula
= - 9
The common ratio r = - 9 and with a = 300, then
= 300 → C
Answer:
Probability (N more than 2) = 0.3773
Step-by-step explanation:
Given:
Average number of crashes (N) = 2.2
Find:
Probability (N more than 2)
Computation:
Probability (N more than 2) = [1-P(N=0)-P(N=1)-P(N=2)]
Probability (N more than 2) = [1 - e⁻²°² - 2.2e⁻²°² - (2.2²e⁻²°²)/2]
Probability (N more than 2) = 0.3773
