If you flipped the coin 100 times, how many heads would you expect to get? Explain your answer.
Irina18 [472]

Answer:

You would expect to get 50 heads

Step-by-step explanation:

Each time you flip a coin you will either get heads or tails. This means that you have a 1/2 probability of getting heads. If you use this then you need to multiply 1/2 and 100 to get the expected amount of heads. Multiplying by a half is just dividing by 2. Therefore, the answer is 100/2 = 50. The answer is 50 heads
