An experiment is conducted where a single die is rolled 15 times. A 3,2,1,6,4,6,6,5,2,6,5,3,2,3 and 1 are rolled. What is the probability of rolling a 1? Decimal and fraction form
How many of those numbers are 1s? How many numbers are there in total? put the first answer over the second one and that should be the fraction. Simplify if needed. To find the decimal, use the first answer and divide it by the second answer.
I believe the fraction form is 2/15 and I think that you just have to convert 2/15 to a decimal which is 0.133333 but you might wanna double check.
the probability for rolling a 1 is 1/6. Since there is only one 1 on a die and there are 6 total numbers you first fraction would be 1/6. and since you are rolling the die 15 time, you will multiply 1/6 by 15 to get the probability of rolling a 1 in 15 tries. so the probability is 2 1/2 or 2.5
all probabilities are less than 1.
the answer in fraction form is 2/15, as 2 is 2 numbers out of 15. The decimal is 0.133333.
To calculate the probability of rolling a specific number on a die, we need to know the total number of possible outcomes and the number of favorable outcomes.
In this case, the die is rolled 15 times, and we are interested in the probability of rolling a 1. We have the following data:
Number of times a 1 is rolled: 2
Total number of rolls: 15
To calculate the probability, we divide the number of favorable outcomes (the number of times a 1 is rolled) by the total number of possible outcomes (the total number of rolls).
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 2 / 15
In decimal form, the probability of rolling a 1 is approximately 0.133, rounded to three decimal places.
In fraction form, the probability can be simplified to 2/15.
