A number cube is rolled 360 times, and the results are recorded as follows: 61 ones, 26 twos, 36 threes, 76 fours, 73 fives, and 88 sixes. What is the experimental probability of rolling a 2
or a 3?
The total number of times a 2 or a 3 was rolled is 26 + 36 = 62.
The experimental probability of rolling a 2 or a 3 can be found by dividing the number of times a 2 or a 3 was rolled by the total number of rolls:
experimental probability = number of times a 2 or 3 was rolled ÷ total number of rolls
experimental probability = 62 ÷ 360
experimental probability = 0.1722 or about 17.22%
Therefore, the experimental probability of rolling a 2 or a 3 is approximately 17.22%.
what do polish people find atractive
Just like with any other culture, what is considered attractive in Poland can vary depending on personal preferences. However, some traits that are generally considered attractive in Poland include:
1. Physical appearance: Polish people often value physical appearance and may find certain features like blue eyes, blond hair, and tall height to be attractive.
2. Good manners: Polish people place a great deal of emphasis on good manners, including being polite, courteous, and respectful towards others.
3. Sense of humor: A good sense of humor is often appreciated in Polish culture, as it can help break the ice and make social interactions more enjoyable.
4. Education: Higher education is often valued in Poland, and having a good education or professional qualifications can be considered attractive.
5. Family values: Family is highly important in Polish culture, and individuals who place a high value on family and keeping close relationships with loved ones are often seen as attractive.
what do polish people look like
Polish people have diverse physical appearances and can vary in skin tone, hair color, and facial features, as there is no single "Polish look." Historically, Poland has been influenced by various cultures due to its geographical location, including Germanic, Scandinavian, Baltic, and Slavic cultures, which has contributed to the diversity of physical appearances in Poland.
However, some common physical features that may be associated with Polish people are light to olive skin tones, a range of eye colors including blue, green, and brown, and hair colors that include blond, brown, and black. Additionally, some people of Polish descent may have distinct facial features such as high cheekbones, prominent noses, and full lips. It is also worth noting that Poland is a multicultural country where people of various ethnicities, religions, and nationalities live together, which adds to the diversity of physical appearances.
To find the experimental probability of rolling a 2 or a 3, we need to add the number of times a 2 was rolled to the number of times a 3 was rolled and then divide that sum by the total number of rolls.
First, let's find the total number of times a 2 or a 3 was rolled:
Number of times a 2 was rolled: 26
Number of times a 3 was rolled: 36
Now let's add these numbers together to find the total:
Total = 26 + 36 = 62
Next, we need to divide this total by the total number of rolls:
Total number of rolls: 360
Now let's calculate the experimental probability by dividing the total by the total number of rolls:
Experimental probability = Total / Total number of rolls
Experimental probability = 62 / 360
Using a calculator, we can find that the experimental probability is approximately 0.1722, or 17.22%.
To find the experimental probability of rolling a 2 or a 3, we need to divide the total number of times a 2 or a 3 is rolled (i.e., the sum of the occurrences of 2 and 3) by the total number of rolls (360).
To compute this:
1. Count the number of times a 2 or a 3 is rolled: In this case, the number of times a 2 or a 3 is rolled is 26 (occurrences of 2) + 36 (occurrences of 3) = 62.
2. Divide the total number of times a 2 or a 3 is rolled by the total number of rolls: So, the experimental probability of rolling a 2 or a 3 is 62 ÷ 360 = 0.1722 (rounded to four decimal places).
Therefore, the experimental probability of rolling a 2 or a 3 is approximately 0.1722.
