Medal!! help!

You conduct an experiment where you roll a die and record the results. You roll the die 1230 times and the results are shown in the table below:

What is the experimental probability of rolling a "1" on your next roll?
A. 0.1667
B. 0.1992
C. 0.245
D. 0.3275

@blurbendy  can you help me please?

blurbendy · Answer

wait, you're sure it's not C ?

anonymous · Answer

yep, i got that one wrong last time, so im checking through again to make sure i get the correct answer

blurbendy · Answer

and the frequency on the last one isn't 375, it's 0.375?

anonymous · Answer

yep

anonymous · Answer

its 256 my bad.

anonymous · Answer

so the last one on frequency is 256 lol.

blurbendy · Answer

ah!  okay, then it's B

experimental probability = # times event occurs/total number of events

so you roll a 1, 245 times, and the total number of events is 245 + 172 + 219 + 201 + 137 + 256 = 1230

= 245/1230 = 0.19918699187 which is basically B
