What is probability if repeated events?
When an event is repeated, the probability of it occurring is squared. For instance, if an outcome had the probability of 1/4, then the outcome happening twice would have a probability of 1/16. Note, however, that this does not mean that the second event has different probabilities. That particular outcome will always be 1/4, regardless of anything that happened before it.
How many outcomes are there when a die is rolled twice?
6 possible numbers to land on the first time, 6 possible numbers to land on the second time, 6x6=36
What is the probability of the coin landing heads up twice and tails up one?
What is the chance of it landing on heads twice in a row?
How many different combinations are possible if a coin is tossed twice and a number cube is tossed once?
18 different combinations. When a coin is tossed twice there are four possible outcomes, (H,H), (H,T), (T,H) and (T,T) considering the order in which they appear (first or second). But if we are talking of combinations of the two individual events, then the order in which they come out is not considered. So for this case the number of combinations is three: (H,H), (H,T) and (T,T). For the case of tossing a die once there are six possible events. The number of different combinations when tossing a coin twice and a die once is: 3x6 = 18 different combinations.
What numbers are a mode of 6?
The statistical mode of a set of numbers is the number(s) that occur the most times. There is no mode for a single number. If the set of numbers was 3, 4, 1, 3, 5, 2, for example, the mode is 3, since it occurs twice.
