2. Determine the experimental probability of getting a head (or a tail) by tossing a coin 15 times and
compare it with its theoretical probability.

Objective / Aim : To find Probability of Head / Tail in tossing a coin and compare with theoretical probability
Material Required = Coin
Procedure : Flip the Coin & Note the Result
H H T H T H H T T H H T H T H H
Count Number of Heads & Tails
Coin Flipped number of times = 15
Head turned up = 9
Tail Tuned up = 6
Probability of Head = ( number of times head turned up )/ (Total number of times coin flipped)
= 9/15
= 3/5
= 0.6
P(H) = 0.6
Probability of Tail = ( number of times Tail turned up )/ (Total number of times coin flipped)
= 6/15
= 2/5
= 0.4
P(T) = 0.4
Theoretical probability = P(H) = P(T) = 1/2 = 0.5
Observation : P(H) = 0.6 & P(T) = 0.4
Result : Experimental probability is not same as Theoretical probability
