Fourty-four percent of a corporation’s blue-collar employees
were in favor of a modified health care plan,
and 24% of its blue-collar employees favored a proposal
to change the work schedule. Thirty percent of
those favoring the health care plan modification, favored
the work schedule change.
a. What is the probability that a randomly selected
blue-collar employee is in favor of both the modified
health care plan and the changed work schedule?
b. What is the probability that a randomly chosen
blue-collar employee is in favor of at least one of
the two changes?
c. What is the probability that a blue-collar employee
favoring the work schedule change also favors the
modified health care plan?
In a sample of 100 students enrolling in a university, a questionnaire indicated that 45 of them studied Fashion, 40 studied Textile, 35 studied Drafting, 20 studied both Fashion and Textile, 23 studied both Fashion and Drafting, 19 studied both Textile and Drafting, and 12 studied all three languages.
Using a Venn diagram, find the probability that a randomly chosen student studied only one of the three languages.
For the function tan^(−1) 𝑥 find the infinite Taylor series at 𝑎 = 0, the radius of convergence, range of convergence, derivative, integral and the product with itself.
Let={2,4,7},B={2,5,4} find the set A∆B
Given that ∑ 𝑢𝑘 ∞ 𝑘=1 converges with 𝑢𝑘 > 0, prove that ∑ √𝑢𝑘.𝑢𝑘+1 ∞ 𝑘=1 also converges. Show that the converse is also true if 𝑢𝑘 is monotonic.
Let 𝑥𝑘 be a Cauchy sequence and 𝑓 be a continuous function, show that 𝑓(𝑥𝑘) is also a Cauchy sequence.
