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).

What is the number of elements in an event space for rolling an even number on a single die?
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}.
What is the probability of rolling a number that is divisible by two on a six sided die?
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
If you are going 300 mph in a car ad you rolled out would you survive?
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.
What is the standard deviation of 24?
Standard deviation of a single event is 0.
If You roll a fair number cube twice What is the probability of rolling two threes if the first roll is a 5?
2/36 what you rolled the first time has nothing to do with the next roll. It's an independent event.
Two standard dice are rolled Let A be the event that the first die lands on a number larger than 4 Let B be the event that the second die lands on a number larger than 2 Which of these are true?
A. P(A ans B) = 1/6 &' D. P(B) = 1/6

What is it called when the second number is a facotor of the first number?
In that event, the first number is called a "multiple" of the second number.
What is the Olympic A standard?
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."
What is the probability of getting a sum of 6 or 7 or 8?
The experiment is not defined! The probability of the event described, when 9 or more number cubes are rolled, is 0.
What is the probability of rolling a number that is divisible by two on a six sided die?
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.

Find the probability of each event when two fair number cubes are rolled?
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
What the definetion of frequency?
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.
Which event event occurred second?
The constitutional convention occurred second.
What is the standard deviation of 24?
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.
