Homework Help: Math

Posted by Tori on Wednesday, October 27, 2010 at 9:13pm.

Your teacher has a large box containing an equal number of red and blue folders. There are 24 students in your class. The teacher passes out folders at random. Ten students recieve a red folder. Compare the experimental probability of recieving a red folder with the theoretical probability of recieving a red folder.

Please help! I'm so confused!

half are red so p = 1/2 = .5

theory = (1/2)(24) = 12 students get red

experiment = (p exp) (24) = 10
so
p exp = 10/24 = .417 instead of 0.5
