Isla flipped a coin 30 times. the coin landed heads up 9 times and tails up 21 times.

part a: based on the results, what is the experimental probability of the coin landing heads up? show your work. (5 points)

part b: what is the theoretical probability of the coin landing heads up? show your work. (5 points)

both are equal

Step-by-step explanation:

there are two side tails and heads so there a 1/2 chance it will land on heads

Part A: The experimental probability would be 9/30. I say this because the coin landed heads up 9 times out of 30 flips.

Part B: I would say that the theoretical probability of the coin landing heads up would be 50% or 15 times. I say this because the coin has 2 sides, heads and tails. So, that means you would have a 50/50 chance. So therefore I would say the theoretical probability would be 15 times or 50%.
