Rework problem 7 from section 4.3 of your text, involving filling in the missing entries in a probability density function. Use the following density function instead of the one in your text.   Value of X Probability Product -4 (A) -0.4 -3 (B) -0.3 (C) 0.6 -1.2 -1 0.2 (D) (1) What is the value of (A)?  (2) What is the value of (B)?  (3) What is the value of (C)?  (4) What is the value of (D)

The figure above shows the probability density function for the random variable x. What is P(3≤x<7)?

Find the probability ​P(Ec​) if ​P(E)=0.17.

Determine whether the following are valid probability models or not. Type "VALID" if it is valid, or type "INVALID" if it is not.

Grade A B U Frequency 5 a 9 7 D ** F 5 Refer to the table. Given that receiving at least a C is passing the course, calculate the probability a student passed the course.

In each case, determine the value of the constant c that makes the probability statement correct. (Round your answers to two decimal places.) USE SALT (a) (c) = 0.9857 2.189 (b) P(0 ≤Z≤ c) = 0.3133 0.89 (c) P(C ≤ Z) = 0.1335 1.11 You may need to use the appropriate table in the Appendix of Tables to answer this question.

Hi there, Please answer all the multiple question from the chooise below, no show work needed.  Thank you for quick response. God bless

Assume that the coin is flipped 4 times, and the random variable X is defined to be 2 times the number of heads minus 4 times the number of tails. How many different values are posslbe for the random variable X? Answer: 5 Fill in the table below to complete the probability density function. Be certain to list the values of X in ascending order Values of X (these are all correct. I need help with finding the probabilities) -16, -10, -4, 2, 8 What are the probabilities? Thanks!

I need help with developing the excel formula to calculate the probability for the 5th question of this assignemnt. In this tab, you must answer the five questions below the table of data. To do so, you will have to write formulas which calculate probabilities. To write these formulas, remember the following formula for classical probability: ?(?) = ?/ ?  = ?????? ?? ???? ????? ? ?????? / ????? ?????? ?? ???????? ???????? ?? ?ℎ? ?????? ????? Each of the questions involves a different “X”, and some of them involve different “T”s. Think through each question carefully to make sure you identify these values correctly. Question 5 What is the probability that someone with some college or more makes $75,000 or more?
