What are the odds of rolling a 6 or an 8 before rolling a 7 in craps?
Here are the odds in craps: 7 vs. 6 Odds: 6 to 5 7 vs. 5 Odds: 6 to 4 or 3 to 2 7 vs. 4 Odds: 6 to 3 or 2 to 1 7 vs. 3 Odds: 6 to 2 or 3 to 1 7 vs. 2 Odds: 6 to 1
What are the odds of getting two even numbers when rolling two dice?
The odds are 1:3. The probability is 1/4 or 25%.
What does an odds ratio of 0.5 mean?
It means there is a chance of being right 2 times out of three. 2:1 odds means 1 chance of 3 to be right; 1:1 odds means an even chance; 1:2 (0.5)odds is 2 of 3; 1:9 is 9 chances of being right out of 10 etc.
What are the odds of rolling less than a 4 by rolling the die once?
There are 6 numbers on a die. 3 of those are less than 4 (i.e. 1, 2 & 3). The probability is therefore 3/6 = 1/2.
What is the probability that you will roll a number less than 3 and flip heads if you roll a six-sided die and toss a coin?
1 and 2 are the only two numbers less than 3 so the odds of rolling a number less than 3 is 2/6 or 1/3. Now the odds of heads is 1/2. We use the multiplication rule and we have 1/2x 1/3=1/6 so the odd are 1 in 6
If you toss 3 coins what are the odds of getting exactly 3 heads?
The odds of getting 3 heads in a toss of 3 coins is 1 in 8, or 0.125. Each coin is probabalistically unrelated to each other, so you simply multiply the odds for each coin. 1 in 2 times 1 in 2 times 1 in 2 is 1 in 8.
What are the odds of getting even number in 1 try in numbers 1 to 11?
The numbers from 1 to 11 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The even ones are 2, 4, 6, 8, 10, so there are five even numbers. An even number is a number that is divisible by 2. Any number that is not even is called an odd number. So the odd numbers are 1, 3, 5, 7, 9, 11. We have five even numbers and six odd numbers. Therefore, the odds are 5/11 that we get an even number in one try. The odds that we get an odd number are 11-5/11=6/11. This means the odds of getting an even number are just a little less than getting an odd number.

Probability of getting an even product when rolled 2 dice?
I'm assuming you multiply the numbers rolled. Thus the rules of even and odd numbers come into play. The only way to get an odd product is to roll two odd numbers. The probability desired is 1 minus the probability of rolling two odd numbers. The odds of rolling an odd number is 1/2. Since the rolls are independent events, the odds of rolling two odd numbers is (1/2)2 = 1/4 So the probability of getting an even product is: 1 - 1/4 = 3/4
What do these number series represent 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1?
These are all sets (1,2,1) (1,3,3,1) (1,4,6,4,1) (1,5,10,10,5,1) associated with probability. Let's take a coin flip, 50% heads and 50% tails. You flip it twice - what are the odds of 2 heads, 1 head, 0 heads. The ratio of odds would be 1:2:1. Flip it 3 times and the odds of 3 tails, 2 tails, etc. follow a ratio of 1:3:3:1. Arithmatically, these numbers follow a pattern. 1 x(2/1)= 2 x(1/2)= 1 // 1 x(3/1)= 3 x(2/2)= 3 x(1/3)= 1 // 1 x(4/1)= 4 x(3/2)= 6 x(2/3)= 4 x(1/4) = 1 and so on... Another way to look at these is through addition of 2 consecutive numbers of the preceding series. For example, from (1,2,1), you have 1, then 1+2, then 2+1, then the last 1 or (1,3,3,1). Then 1, 1+3, 3+3, 3+1, and the last 1 or (1,4,6,4,1). So the next series would be (1,6,15,20,15,6,1) and then (1,7,21,35,35,21,7,1).
