The first event is Less than 4, which is either 1, 2, or 3. The probability of this is 1/2.
The second event is die number = 5. The probability of this is 1/6.
Multiply the two probabilities together: (1/2)*(1/6) = 1/12 (about 8.33 % chance).
The even numbers that can be rolled on a single die are 2,4, and 6 so the number of elements in the event space is 3. X={2,4,6}.
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
This is a very situational event. What are you driving? Are you wearing a helmet. There have been people who have rolled cars at 300 mph and lived. But there are people who have rolled cars at 30 mph and died.
Standard deviation of a single event is 0.
2/36 what you rolled the first time has nothing to do with the next roll. It's an independent event.
A. P(A ans B) = 1/6 &' D. P(B) = 1/6
The even numbers that can be rolled on a single die are 2,4, and 6 so the number of elements in the event space is 3. X={2,4,6}.
In that event, the first number is called a "multiple" of the second number.
The experiment is not defined! The probability of the event described, when 9 or more number cubes are rolled, is 0.
The A Standard is the "automatic" qualifying time for an event. The B Standard is the backup qualifying time. To be guaranteed a spot in an Olympic event, you must both earn a slot from your country (number of slots may vary by event and by country) and have achieved the A standard. If there are not enough participants around the world who have qualified that way, then competitors with B Standard times may be added to "make the event competitive."
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
This is a very situational event. What are you driving? Are you wearing a helmet. There have been people who have rolled cars at 300 mph and lived. But there are people who have rolled cars at 30 mph and died.
The probability that any number will come up on one cube is 1/6. 1/6*1/6=1/36 the probability is 1/36
Frequency is the number of times a repeating event occurs in a period of time. For example 60Hz or 60 times per second means a repeating event occurred 60 times in 1 second period.
The constitutional convention occurred second.
Standard deviation of a single event is 0.
2/36 what you rolled the first time has nothing to do with the next roll. It's an independent event.
