So You are flipping 2 coins at the same time for 100 times. The results you can get are two head, two tails or one head and one tail. But what does it mean when their asking about frequency? like 27 out of 100 coin flips??

Question

amistre64 · Answer

frequency, how many times do you expect something to occur ...

amistre64 · Answer

hh
ht
th
tt

hh is expected 1/4 of the time:  freq = 100(1/4)
tt is expected 1/4 of the time: freq = 100(1/4)
th is expected 1/2 the time:  freq = 100(1/2)

amistre64 · Answer

the sum of the freqs is the total of number of events

amistre64 · Answer

if its an experimental run, then its just the number of times it occured during the experiment

anonymous · Answer

Well I'm supposed to flip 2 coins (at the same time) 100 times and then record my answers.

amistre64 · Answer

start flippin :)

anonymous · Answer

And how would you know that hh is expected those times. I already flipped them

amistre64 · Answer

theoretical probabilty ..

amistre64 · Answer

the only possible outcomes are:

hh
th
ht
tt

hh has 1 out of 4 chances ...

anonymous · Answer

the theoretical probability would be 1/3 because there are 3 results you could get: Two heads, two tails, and one head and one tail

amistre64 · Answer

no,  thats not how you work it

amistre64 · Answer

th  and ht are both possible outcomes with the same effect

amistre64 · Answer

th and ht happen 1/2 the time in theory

anonymous · Answer

then how? Can u try to explain it with my problem

amistre64 · Answer

your problem is an experiement, there is no explaining it other than counting up the results.

amistre64 · Answer

we would expect, as you do 1000s and 1000s of flips,  that the experimental probability would approach the theoretical probability ...

anonymous · Answer

Well I'm trying to figure out the theoretical and experimental probability of events while doing the experiment. I'm saying that the theoretical probability would be 1/3 because there are 3 results you could get: Two heads, two tails, and one head and one tail. But idk the experimental probability. I also don't know what it's talking about when it's say's frequency.

amistre64 · Answer

frequency, counting the number of times something occurs ... 

lets make a table ....
