will fan+medal!! PLEASE HELP!! The table shows the results of rolling a number cube labeled one through six 50 times. # rolled Frequency 1 7 2 9 3 11 4 6 5 9 6 8 What is the experimental probability of rolling an 3? a. 0.11 b. 0.22 c. 0.30 d. 0.27

OpenStudy (anonymous):

hi again @Garrett372 could you please help me with this one too? : )

OpenStudy (anonymous):

add the all of the frequencies up and tell me what you get

OpenStudy (anonymous):

i got 50

OpenStudy (anonymous):

now divide 11/50

OpenStudy (anonymous):

0.22?

OpenStudy (anonymous):

and that is your answer :)

OpenStudy (anonymous):

awesome! thanks!

OpenStudy (anonymous):

yes, i am also good at chemistry, environmental science, and most other sciences

OpenStudy (anonymous):

so if you need help with those i can

OpenStudy (anonymous):

could you help with my 3 last questions for the day?

OpenStudy (anonymous):

wow!! you're good at this stuff

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

i am about to go to lunch so can i answer your other 2 in 30min?

OpenStudy (anonymous):

but i can answer your first one

OpenStudy (anonymous):

Based on the experimental probability, predict the number of times that you will roll a 5 if you roll the number cube 300 times? a. 15 b. 27 c. 48 d. 54

OpenStudy (anonymous):

yeah thats totally fine!

OpenStudy (anonymous):

the only answer im getting is 50

OpenStudy (anonymous):

are you sure those are the answers?

OpenStudy (anonymous):

yeah, I'm sure

OpenStudy (anonymous):

Yeah because there are 6 sides on a cube, and 6 different possiblitys every time. So you have 1/6 chance of rolling 5 every time... So you multiply that by 300 and you get 50

OpenStudy (anonymous):

hmm...

OpenStudy (anonymous):

I would put 48 if i were you that is your best guess.

OpenStudy (anonymous):

ok thank you!

OpenStudy (anonymous):

alright i will be back in 30 if no one else answers your questions

OpenStudy (anonymous):

thanks, bye!! don't worry about me

OpenStudy (anonymous):

you still need help?

OpenStudy (anonymous):

no I am good now...but thanks!
