can anyone me answer these questions and determine whether they are experimental or theoretical probabilities ? soon as possible!
i want the correct answers no guessing.

theoretical vs. experimental

identify whether the described situation is an example of experimental probability or theoretical probability.

a) i just flipped a coin several times and the coin landed on heads more than tails. 6 times on heads and 5 times on tails. the probability of landing on heads is 6/11.

b) there are 10 marbles in a bag. 3 are red, 3 are blue, and 4 are green. the probability of pulling a red marble from the bag is 30%.

c) on a dice there are 6 sides. the probability of rolling an even number is 50%.

d) based on conclusions from a class survey, 85% the class would like extra credit.
