Check all the statements that are true:A. If A and B are mutually exclusive events, the probability for the event (A and B) is zero. B. If an experiment has n possible outcomes, each outcome has probability 1n1n. C. In probability theory, an event is one possible outcome of an experiment. D. The probability for an event may be zero. E. If A and B are different events, the probability for the event (A and B) is zero. F. If an event has a probability of 50%, then, if the random experiment is carried out 100 times, it is unlikely, though not impossible, that the event will occur less than 10 times. G. If an event has a probability of 50%, then, if the random experiment is carried out 10 times, the event will occur exactly 5 times. H. The probability for an event may be larger than 1.I. If event A has probability p1p1 and event B has probability p2p2, then the event (A or B) has probability p1+p2p1+p2.J. If a random experiment has n possible outcomes, then there are exactly 2n2n many events associated with the random experiment.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

John used linear combination to solve the system of equations shown. he did so by multiplying the first equation by -3 and the second equation by another number to eliminate the x-terms. what number did jonas multiply the second equation by? 4x-6y=23x+5y=11
