Tobacco use is seen as the primary wellspring of preventable passing and disease in the United States. The National Survey on Drug Use and Health gives information on drug use in the United States. Following is a table appearance the amounts of individuals, by age class and sex, who have a ton not smoked a cigarette inside the earlier month. Numbers (in Thousands) Who Have a ton Not Smoked a Cigarette Within the Past Month, by Age and Gender (Numbers in Thousands)
Age Category
Female

a What is the probability that a self-assertively picked individual in the United States smoked a cigarette during the earlier month? b What is the probability that a discretionarily picked individual developed 12 to 17 smoked a cigarette during the earlier month? c What is the probability that an erratically picked male smoked a cigarette inside the earlier month?
d What is the probability that a self-assertively picked female smoked a cigarette in the earlier month?
Question 34
A piece of an electrical circuit is shown immediately. The switches work unreservedly of each other, and the probability that each hand-off closes when the switch is thrown is appeared by the switch. What is the probability that current will move from s to t when the switch is thrown? 0.9 0.8
0.9
Question 35
Three events, A, B. in addition, C, should be free if the going with balances hold: P (AB) = P(A)P(8) P (AC) = P(A)P(C) P ( BC ) = P(8)P(C) P (ABC) = P(A)P(8)P(C) Suppose that a fair coin is self-rulingly tossed on different occasions. Events A, 8, and C are described as follows: A: Heads comes up on the chief toss. 8: Heads comes up on the resulting toss. C: Both tosses yield a comparable outcome. Are A. 8, and C independent? Legitimize your answer.
Question a day and a half
Circuit sheets from two consecutive development frameworks set up to make indistinct sheets are mixed in one storing plate. As evaluators examine the sheets, they find that it is difficult to choose if a board comes from line An or line B. A probabilistic evaluation of this request is routinely valuable. Expect that the limit plate contains 10 circuit sheets of which six came from line An and four from line B. An inspector picks two of these indistinct looking sheets for examination. He is enthusiastic about X, the amount of inspected sheets from line A.
a Find the probability work for X. b Graph the probability limit of X. c Find the movement limit of X. d Graph the dissemination limit of X.
