I really need help
Experimental probability is defined as the proportion of the favorable event: # observed favorable / # observed total
I get that but how do I answer this question :(
what is the number favorable here
I need help with the experimental question.
30 is the total , not the number favorable
Then it is 9?
So it is 9/30 = 0.3 21/30 = 0.7.
I'll metal them please help!
What is the experimental probability?
\(Experimental\) means what you get after you flip the coins and count the number of heads. In this case you (actually Isla) counted 9. You tried 30 times so the experiment predicts that the probability of heads is 9/30. The theoretical solution is what you get by making assumptions. The easiest assumption is that the number of heads and the number of tails should be about the same after many many experiments. Right? So if you expect an equal number of heads and an equal number of tails, how many heads would you expect after 30 flips of the coin? You'll get #heads/30 = 0.50, which is the theoretical probability of heads. Hope this helps.
