Suppose you roll one die find the probability of not rolling an even number?
Not even is odd. Odd is 1,3,& 5 which is 1/2 of the numbers on the die. Therefore the probability of not rolling an even number is 1/2 or 0.5.
What is the probability of rolling an even number on a number cube labeled 1 through 6?
1/2 - you have a 50-50 chance of rolling an even number (or an odd number for that matter !)
Find the probability of rolling a 2 on a number cube and then an even number on two consecutive rolls of a number cube?
1/6,3/6 ----------------------------------------------------------------------------------------------------- The probability of rolling a 2 is: P(2) = 1/6 The probability of rolling an even number is: P(even) = 1/2 The result on the second roll is independent of the result in the first roll. The probability of rolling a 2 and then rolling an even number is: P(2,even no.) = (1/6) ∙ (1/2) = 1/12 = 0.08333... ≈ 8.33%
What is a complementary event?
For any event, the complementary event is all of the other possible outcomes. For an event (Rolling a number cube) " Rolling an odd number " The complementary event is " Rolling an even number "
A die is tossed. Find the odds against rolling a number greater than 1.?
The probability of rolling a number greater than 1 is 5/6.
Suppose you roll one die what is the probability of rolling an even number?
As there are an equal number of odd and even numbers on a single die, the odds of rolling an even number would be 50/50.
What is the probability of rolling an even number or prime number on a number cube?
The probability of rolling an even number on a die is 3 in 6 or 1 in 2. The probability of rolling a prime on a die is 3 in 6 or 1 in 2, but one of those primes is also even. Simply add the probabilities and you find that the probability of rolling an even number or a prime on a die is 5 in 6.
What is the probability of rolling an even number and a head when rolling a die and then tossing a coin?
-3/12
What is the probability of rolling an even number on a die and rolling an odd number on a second roll of the same die?
0.25 ( P = 0.5 each time)
What is the probability of rolling an even number on an eight-sided die?
Assuming that there are an equal number of even and odd faces on the eight-sided die, then the probability of rolling an even number is simply 4 in 8, or 1 in 2, or 0.5.
What is the probability of rolling a 2 on a die and then re-rolling the die and getting an even number?
The probability of rolling a 2 is 1 in 6. The probability of rolling an even number is 3 in 6. The probability of doing both, on two rolls, is 3 in 36, or 1 in 12.
How many outcomes are there in the rolling a die in an even number?
there's 1/3 chance of getting an even number in a die, hon
What are the odds of rolling an even number when using a die?
one half.
Suppose you roll one die find the probability of not rolling an even number?
Not even is odd. Odd is 1,3,& 5 which is 1/2 of the numbers on the die. Therefore the probability of not rolling an even number is 1/2 or 0.5.
If you roll a six sided dice six times you will roll an even number at least once True or False and how did you get it?
You have a 3.125% chance of not rolling an even number, because each time you roll a die you have a 50% chance of not rolling an even number, but each additional time you roll a die your chances of not rolling an even number the formula changes from 3/6 to 3/12 because the possibilities double but your chances of not rolling an even remain the same so eventually we end up with 3/96 because of rolling the die 6 times.
What is the probability of rolling an even number on a standard six-sided die?
It is 0.5
What is the probability of rolling an even number on a standard 6 sided die if an even number is rolled 7 times out of 12?
A standard die has no memory and so the probability of rolling an even number is always a half. If you did not know that the die was standard and were using the fact that 7 out of 12 rolls were even as an empirical estimate for a loaded die then the answer is 7/12.
