    yo... well a certain event... probability would be 100%, yeah? and an impossible event... probability would be 0%, so can't happen

    yep, so 2 possible outcomes, and unless its a weighted or double sided coin, it's a 50 50 chance, so 50% change of landing heads and 50% chance of landing tails

    so for 2 it is 100 cause it is 50 50 correct?

    exactly = 100 for Q2, perfect. 50% x 200 = 0.5 x 200 = 100

    experimental vs theoretical... yep so the experimental probability is the one you (like srsly u) get if u were to do the experiment so if u experiment and only flip a coin 10 times, and it comes down heads 7 times and tails 3 times... your experimental probability for heads is 7/10 = 0.7 = 70%

    but u know for a coin, the theoretical probability is 50% heads... so if u kept flipping it like 100 times, you'd get closer and closer to the theoretical prob, yeah?

    4. well, it's a standard coin... because it doesn't say that it's not, so regardless of the outcome of the last 200 or 1 million flips, the probability of heads is still 50% every time the coin's flipped
