Do you know what *theoretical* and *experimental* probabilities are?

yes

  • SolomonZelman
What is the *theoretical* probability in this case?
anonymous
  • anonymous
i dont really know :(
SolomonZelman
  • SolomonZelman
Yes, you do. The theoretic probability for either one a head or tails is 1/2. (because there are two possible outcomes and one "desired" outcome, which thus comes out to 1/2)
SolomonZelman
  • SolomonZelman
Did that make sense just now, or not?
anonymous
  • anonymous
yes
SolomonZelman
  • SolomonZelman
Yes, good. (Because in *theoretic* probability we aren't considering what happened in the experiment and the experiment's conclusion)
SolomonZelman
  • SolomonZelman
Now, what is the *experimental* probability for *heads* in group *G*?
anonymous
  • anonymous
i dont know
SolomonZelman
  • SolomonZelman
Group G conducted 50 trials, and only 34 of them were heads. So, since in the experiment there were 34/50 heads, thus the *experimental probability of heads* (or the chance that the heads will come out on the coin toss, - based on the experiment) is equal to: *34/50* (you don't need to reduce the fraction)
SolomonZelman
  • SolomonZelman
So, *Experimental Probability (Tossing Heads) = 34/50*

  • SolomonZelman
Yes.
SolomonZelman
  • SolomonZelman
Can you find the *experimental probability* of *Tails* in group *G*?
anonymous
  • anonymous
no :(
SolomonZelman
  • SolomonZelman
(Hint: How many trials were there altogether in group G? How many of these trials were tails in group G? ) {answer the hint questions please}
