Please answer all parts of question. Thank you!
Discrete Probability Distributions: part 1 1. Consider the experiment of rolling two dice. a.) Define a random variable that takes on all possible values for the minimum value of the two dice face showing when the dice come to rest after the roll. b.) Before doing anything at all (do not write out the distribution yet), think about this experiment and the random variable. Tell me what you think the shape of...

Please help with PYTHON exercise 1 below:
Write a program Sores.py to process a student's homework scores. Ask user to enter the homework scores for a student and save the scores in a list. Loop through the list to find the total score and the lowest score. (Do not use built-in function, sum and min. You need to write a loop to process the scores). Calculate the raw average score and modified average score (after dropping the lowest score). Print...

A study was conducted to assess the effects that occur when children are exposed to cocaine before birth. Children were tested at age 4 for object assembly skill which was described as a “task requiring visual-spatial skills related to mathematical competence”. The 190 children born to cocaine users had a mean of 7.3 and a standard deviation of 3.0. The 186 children not exposed to cocaine had a mean score of 8.2...
