Probability of a tsunami on the east coast of the US?

Very close to 1. Over the next 4.5 billion years that the earth is expected to remain in existence, such an event is almost certain.


If you draw a card from a standard deck of cards what is the probability of drawing a spade?

To determine probability you do Number of Times the Desired Event will occur -------------------------------------------------------- Number of Possible Outcomes In this case, there are 52 cards in a deck (assuming no jokers). 1/4th of those cards are spades (This gives us 13 spades) so Number of Times the Desired Event will occur = 13 Number of Possible outcomes = 52 You will draw a spade 13 out of 52 times. (13/52) Or reduced - You will draw a spade 1 out of 4 times (1/4)


What does probable mean in math?

The dictionary dot com states probability as meaning:1. the quality or fact of being probable. 2. a strong likelihood or chance of something: The probability of the book's success makes us optimistic. 3. a probable event, circumstance, etc.: Our going to China is a probability. 4. Statistics. a. the relative possibility that an event will occur, as expressed by the ratio of the number of actual occurrences to the total number of possible occurrences. b. the relative frequency with which an event occurs or is likely to occur.


The average number of days school is closed due to snow during the winter in a certain city in the eastern part of US is 4.what is the probability that the school in this city will close?

The probability of the school in this city being closed is the same as the probability of Iceland being covered in a cloud of ash to the extent of Airplanes being cancelled.....so yea, pretty good :D

The chance that a given event will occur usually expressed between the number 0 and 1?

The chance that a given event will occur is typically expressed as a probability, which is a number between 0 and 1. A probability of 0 means the event will not occur, while a probability of 1 means the event will definitely occur. Probabilities between 0 and 1 give us the likelihood of the event happening.

If the probability that an event will occur is three eighths then what is the probability that the event will not occur on the first trial and not occur on the second trial?

This question does not have a unique answer unless we make an additional assumption: we must know something about the relationship between the trials. For example, if we are monitoring a lightbulb for failure and the "event" consists of a working lightbulb, then the event not occurring means the lightbulb doesn't work. Let the "trials" consist of turning on the lightbulb. If the bulb fails on the first trial (chance of 1 - 3/8 = 5/8) then obviously it will not work on the second trial, either. The answer in this case would be 5/8 = 62.5%. If we assume the two trials are statistically independent, we are really saying we don't want to worry about these issues. Equivalently, the person asking the question is just telling us to multiply the probabilities (which means they are probably a teacher or a textbook and they or it are mainly concerned about your ability to multiply fractions, not about your understanding of probability). The chances of the event not occurring in each trial are 5/8. Multiplying gives 25/64 = about 39%. This is quite a bit less than 62.5%.

After OSUT can a US Army Infantryman choose what Division he will be assigned to?

All US soldiers are given opportunity to fill out what is referred to as a "dream sheet" on which they can request certain assignments. The premise is that assignments to dream sheet units will be issued in the event they are to the benefit of the Army. The reality is that few dreamsheet assignments actually occur.
