Good Evening, I need some assistance getting the awnser for these questions please.
1.) Part 1?
A family has two children. If the genders of these children are listed in the order they are born, there are four possible outcomes: BB, BG, GB, and GG. Assume these outcomes are equally likely. Let ) represent the number of children that are girls. Find the probability distribution of X. Part: 0 / 2 Part 1 of 2 (a) Find the number of possible values for the random variable X. There are possible values for the random variable X.There are 5000 undergraduates registered at a certain college. Of them, 463 are taking one course, 660 are taking two courses, 562 are taking three courses, 1879 are taking four courses, 1342 are taking five courses, and 94 are taking six courses. Let X be the number of courses taken by a student randomly sampled from this population. Find the probability distribution of Y. Round the answers to four decimal places as needed. X 2 4 6 P (x)Following is the probability distribution of a random variable that represents the number of extracurricular activities a college freshman participates in. X 0 1 2 3 4 P(x) 0.07 0.14 0.45 0.21 0.13 Send data to Excel Part: 0 / 3 Part 1 of 3 (a) Find the probability that a student participates in exactly four activities. The probability that a student participates in exactly four activities isCompute the mean and standard deviation of the random variable with the given discrete probability distribution. 3: P (I) 6 0.25 5 0.11 6 0.23 8 0.28 9 0.13 Semi dam to End (a) Find the mean. Round the answer to three decimal places, if necessary. The mean is D. (b)l nd the standard deviation. Round the answer to three decimal places, if necessary. The standard deviation is D. Dirty air: The federal government has enacted maximum allowable standards for air pollutants such as ozone. Let X be the number of days per year that the level of air pollution exceeds the standard in a certain city. The probability distribution of X is given by X 0 1 2 3 P (x) 0.34 0.39 0.19 0.05 0.03 Send data to Excel Part 1 of 6 (a) Find P(3). P(3) =] Part 2 of 6 (b) Find P(2 or fewer). P(2 or fewer) = Part 3 of 6 (c) Find the probability that the standard is exceeded on at least three days. The probability that the standard is exceeded on at least three days is{d} nd the probability that the standard is exceeded on more than one day. The probability that the standard is exceeded on more than one day is [j . (e) Compute the mean \"1- Round the answer to two decimal places. wE] (1") Compute the standard deviation ox.
