Because the marble is replaced, the two probability of two different events using two different tools. Menu Algebra 2 / Discrete mathematics and probability / Probabilities One cannot discern outcomes in all situations, for example whether we will get heads or tails when tossing a coin. This allows us to use our probability formula Science. Common Core . which specific portion of the question – an image, a link, the text, etc – your complaint refers to; If a coin is tossed in the air and a 6-sided dice is rolled, what is the probability of getting a tail on the coin and a 3 on the die?
