Question

A proper unbiased coin was tossed 10 times for 3 trials, giving TTHHTHTTHH, TTTTTHHHHH, and THTHHHTTHT (T = Tails; H = Heads). What is the difference between the theoretical and experimental probabilities of getting heads?

Answer 1

0.0

Explanation:

Edmentum

Answer 2

theoretical probability (head or tail) = 1/2(10) = 50: 50
experimental probabilities:
1st trial: TTHHTHTTHH P(H)= 5 , P(T) = 5 i.e. 50:50
2nd trial: TTTTTHHHHH P(H) =5 , P(T) = 5 i.e 50 50
3rd trial: THTHHHTTHT P(H) =5 , P(T) = 5 i.e. 50 50

These three trials show that , at least in this case, there is no difference between the theoretical probability and the experimental probabilty
