A number cube is rolled 450 times. The number 3 comes up 67 times.
What is the theoretical and experimental probability of rolling a 3 ?
I think the answer is 2/9 but not sure of the process. Can someone explain to me. Sorry to be so much trouble. Thanks
The experimental is 67/450 = 0.14888 = 14.89%
The theoretical is 1/6 = 75/450
Can we just take the time to appreciate the founder of this website. I couldn’t find him/her. But like you don’t even need to put in a email or anything, just a name. And it doesn’t make you watch ads! They just pop up on the side and you don’t have to notice them!
Anyways give this a like if you agree!💜
yk its honestly shocking if connexus doesn't know about this place yet. like its so easy and public. i wonder if they do indeed know it exists but just let us use it anyway lol.
according to your experiment, the 3 came up 67 times out of the 450 rolls.
So the "experimental" probability is
67/450 = .1488...
In theory, it should come up
(1/6)(450) OR 75 times
So what do you think would be the theoretical probability ?
@ someone please help me here its different we acually help each other and learn from one another
they know about it and dont want students to use it, yet we do it anyway..
FAKE MS.SUE B CAREFUL
uuuuhhh
why?
miss sue is right
So what is the real and explained answer?
a. The theoretical probability of rolling a 3 on a number cube is 1/6 because there are six equally likely outcomes (numbers 1 through 6) and only one of them is a 3. Therefore, the theoretical probability of rolling a 3 is 1/6 in simplest form.
b. The experimental probability of rolling a 3 is calculated by dividing the number of times a 3 was rolled (67) by the total number of rolls (450).
Experimental probability = 67/450
This fraction cannot be simplified further, so the experimental probability of rolling a 3 is 67/450 in simplest form.
anywho does anyone have answers
A number cube is rolled 450 times. The number 3 comes up 67 times.
a. What is the theoretical probability of rolling a 3? Write your answer as a fraction in simplest form.
b. What is the experimental probability of rolling a 3? Write your answer as a fraction in simplest form.
I apologize, I did answer the question you posted. Here is the solution to the problem you provided:
A number cube is rolled 450 times. The number 3 comes up 67 times.
a. What is the theoretical probability of rolling a 3? Write your answer as a fraction in simplest form.
The theoretical probability of rolling a 3 is 1/6, since there are 6 equally likely outcomes and only one of them is a 3.
b. What is the experimental probability of rolling a 3? Write your answer as a fraction in simplest form.
The experimental probability of rolling a 3 is calculated by dividing the number of times a 3 was rolled (67) by the total number of rolls (450).
Experimental probability = 67/450
This fraction cannot be simplified further, so the experimental probability of rolling a 3 is 67/450 in simplest form.

good job
9 divided by 3.2=27.
do it urself
yall know yall can't curse on this site so don't say nun
Ms. Sue right?
oh my god.... does anyone have common sense?? USE YOUR BRAIN!!!!
ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhkay
wait I thought you weren't allowed to give answers?
so why did you give answerers?
