Question

carl intends to flip a coin 100 times. what probability model can he use to predict whether or not a particular toss will give a result of heads? each toss has a 0.1 percent chance of a heads result. each roll has a 0.01 percent chance of a heads result. each toss has a 0.5 percent chance of a heads result. each toss has a 0.05 percent chance of a heads result.

Answer 1

Assumptions used to construct the model:

-- The coin has two sides.
-- The probability that the coin will land standing on its edge is zero.
-- The probability that the coin will land with one side up or
the other side up is 100% .
-- The coin is "honest".  The probability of landing on one side
is equal to the probability of landing on the other side.

Conclusions / Probability model resulting from the assumptions:

The probability of either side up is  1/2 = 0.5  =  50% .
