1) DISCUSSION QUESTION
ALEKS Scavenger Hunt: Post one of your questions that you have worked on or are working on in ALEKS. Do not solve it. You just need to post the question as it appears in ALEKS. You should share how this topic relates to the real world or to your current or future career. For your responses to your classmates, pick a submitted problem and share a trick or strategy that you used to conquer that topic. Let me know if you have any questions.
ALEKS PROBLEM BELOW
The workers’ union at a particular university is quite strong. About 96%of all workers employed by the university belong to the workers’ union. Recently, the workers went on strike, and now a local TV station plans to interview 5 workers(chosen at random) at the university to get their opinions on the strike. What is the probability that exactly 4 of the workers interviewed are union members?
Round your response to at least three decimal places. (If necessary, consult a list of formulas.)
2) PEER REVIEW #1 (HEATHER)
One of the problems in ALEKS I have worked on is outcomes and probability. The problem is:
A coin is tossed 3 times. An outcome is represented by a string of the sort HTT (meaning a head and then two tails followed). The 8 outcomes are listed in the table below. Note that each outcome has the same probability. For each of the three events below, check the outcomes that are contained in the event. Then, in the last column, enter the probability.
People use probability all the time. If something keeps occurring over and over again or does not occur at all people use the probably on how often it occurs to guess if it is going to happen again. I work for CVS Pharmacy and our hours are pretty much based on probability. If we were busy last year or a holiday is coming up then corporate uses that to estimate if we’ll be busy the same time next year or quarter. If we were busy last year more than likely being busy will occur again this year. They go back 5 years for this. They use probability to make decisions when we do not know for sure what the outcome will be. Not only in jobs is probability used but also planning around the weather. Weather people can’t predict exactly what the weather will be, so they use different tools and satellites to determine the likelihood of rain, sleet, snow, hurricanes, and also hail. We use probability everyday probably more than what you would ever imagine.
3) PEER REVIEW #2 (MONICA)
I have been working on combinations. The challenge is to cal how many possible outcomes there are given a specified number of sets and number of possible outcomes for each set. In other words, what are the odds of a certain event. The problem I’m referencing asks about music box sets. A musician releases 15 albums. The record company will comprise a boxed set of only 4 albums. So, how many combinations are possible.
I can relate this to real life. I find myself weighing my options and the goal is always to yield the best outcome. What are my chances to get what I want, to have things turn out exactly as I had hoped. Probability gives us a meaningful calculation. I do not gamble, but I do fill out my brackets every year during March Madness. There are 64 teams in the tournament. Only 1 will win. Each has a chance. What is the likelihood of my team winning it all. Probability can be used to solve this. As for combinations, I love pizza. One of my favorite pizza spots has more than the average number of toppings for pizza. This allows the customers creativity and empowers them to customize the pizza. I think this is why the restaurant is so popular. The ten more ingredients than your standard pizza place allows for nearly a hundred more combinations. To each his own….
