Erin has four shirts (white, blue, red, black) and two pairs of pants (blue and black). She randomly chooses a shirt and a pair of pants. What is the probability that they are the same color? i'm so confused about probability. any advice?
Reiny and Ms. Sue at least try to help -.- and it might be simple to YOU but it might not be simple to EVERYONE else -.- and also DA BENGALS RULE DA EARTH did not say he/she does not know how to do it there just confused so, If keeping your job all depended on this question i REALLY think you should be fired Mr. Sue. So please help students and others to pass :)
The answer 1/4
#You'reWelcome
just as a hint, there are 4*2 possible ways to pick the outfit.
How many of those have matching colors?
To find the probability that the shirt and pants chosen by Erin are the same color, we first need to determine the total number of possible outcomes, and then find the number of favorable outcomes.
Total Number of Possible Outcomes:
Erin can choose any one of the four shirts, and any one of the two pairs of pants. Therefore, the total number of possible outcomes is 4 (shirts) multiplied by 2 (pants) which equals 8.
Number of Favorable Outcomes:
Erin needs to choose either the blue shirt and the blue pants or the black shirt and the black pants for the colors to match. So, there are only 2 favorable outcomes.
Now, to find the probability, we divide the number of favorable outcomes by the total number of possible outcomes:
Probability = Number of Favorable Outcomes / Total Number of Possible Outcomes
Probability = 2 / 8
Simplifying this fraction, the probability that the shirt and pants chosen by Erin are the same color is 1/4 or 0.25.
Probability can be thought of as the likelihood of an event occurring. In this case, it is the likelihood of Erin choosing a shirt and pants of the same color. To improve your understanding of probability, here are a few general tips:
1. Understand the Problem: Make sure you clearly understand the question and what is being asked. Identify the key information and the possible outcomes.
2. List all Possible Outcomes: In most probability problems, you need to identify all the possible outcomes. This involves considering different scenarios or combinations and listing all the options.
3. Determine Favorable Outcomes: Once you have the possible outcomes, identify the favorable outcomes. These are the outcomes that satisfy the condition or criteria given in the problem.
4. Calculate Probability: Divide the number of favorable outcomes by the total number of possible outcomes and simplify the fraction, if necessary.
5. Practice Regularly: The more you practice solving probability problems, the more familiar you will become with the concepts and calculations involved.
6. Seek Help if Needed: If you're still confused or struggling with probability, don't hesitate to seek help from a teacher, tutor, or online resources. There are plenty of tutorials, videos, and practice problems available to deepen your understanding.
