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)

Part A.) 0.3 or 30%

Part B.) 0.5 or 50%

Step-by-step explanation:

She flipped the coin 30 times.

She flipped it 9 times for heads.

She flipped it 21 times for tails.

Part A.)

9/30

When you simplify that you get 3/10.

Which is 0.3 or a 30%

Part B.)

So there are only 2 sides of a coin.

Heads or tails, So its a 50 - 50

Hence

For One side it is 50/100

Which simplifies to 1/2

Or 0.5 which is 50%
