A coin is tossed 20 times. The outcomes H (for heads) and T (for tails) are recorded:

H T H T T T T H H T T H H T T T H H H T

What is the experimental probability of getting heads (H)?

0.45

0.5

0.65

0.8

You know the basic definition of probability?

diana.xl · Answer

is my answer 0.45?

aravindg · Answer

How did you get that?

diana.xl · Answer

9/20 = 0.45

aravindg · Answer

Sorry @ayeshaafzal221 I do not agree to that. The question specifically asks for experimental probability, a term which is quite different from theoretical probability. 

@Diana_xL Your answer 0.45 is right.

srry @Diana.xL  and thnx @AravindG  i was thinking theoretically i guess

aravindg · Answer

Theoretical probability is what we expect to happen, whereas experimental probability is what actually happens when we try it out. I hope you realize the difference.
