What is the probability of tossing 2 coins one after the other and getting 1 head and 1 tail?
It's a 50/50% chance of that happening (that's just my guess)
What else can I help you with?
What is the probability of getting exactly 2 tails of tossing a coin?
The probability of getting two tails when tossing a coin is zero, because the coin can only have one result. If, one the other hand, you toss the coin twice, then the probability of getting two tails is 0.25, i.e. the probability of one tail, 0.5, squared.
What is probability of getting head or tail when tossing a coin?
The probability of getting a head or a tail is, for all practical purposes, equal to 1. The only other possibility is that the coin stands on its edge - technically possible but so very unlikely that it can safely be ignored.
What is the probability of not getting a club in a deck of 52 cards?
The probability of not getting a club is the same as the probability of getting one of the other suits. There are (52-13)=39 such possibilities out of 52. Hence the probability is 39/52=3/4.
Seven coins are tossed What is the probability of 3 heads or 2 tails?
The probability of one event or the other occurring is the probability of one plus the probability of the other. The probability of getting 3 heads is the probability of 3 heads (1/23) multiplied by the probability of 4 tails (1/24) multiplied by the number of possible ways this could happen. This is 7c3 or 35. Thus the probability of 3 heads is 0.2734375. The probability of 2 tails is the probability of 2 tails (1/22) multiplied by the probability of 5 heads (1/25) multiplied by the number of ways this could happen. That is 7c5 or 21. Thus the probability of 2 tails is 0.1640625 The probability of one or the other is the sum of their probabilities: 0.1640625 + 0.2734375 = 0.4375 Thus the probability of getting 3 heads or 2 tails is 0.4375.
What is the probability of tossing a single coin and getting 2 heads before you get 3 tails?
5 independent events, each of them with a probability of 1/2; you need to multiply all together, so you get (1/2) to the power 5.Note: any other specific combination you can get when throwing a coin 5 times - for example, head, tails, head, tails, head - will have the same probability.
Three fair coins are tossed at the same time What is the probability that one of the coins will show heads and the other two will show tails?
2/9
What is the probability of not getting a 7 or 11 on either of two tosses of a pair of dice?
First we find the probability of getting a 7. Of the 36 outcomes possible 6 result in a sum of 7, in other words 1/6. The probability of getting an 11 is 2/36 or 1/18. The probability of getting one or the other is the sum of the two, 8/36 or 2/9. The proability of getting neither is equal to the probability of getting anything other than 7 or 8. We find this value by subtracting 2/9 from 1. So the probability of not getting 7 or 11 is 7/9.
What is the multiplication rule?
States that to determine a probability, we multiply the probability of one event by the probability of the other event. Ex: Probability that two coins will land face heads up is 1/2 x 1/2 = 1/4 .
What is the probability of getting a head if coin is tossed 5 times?
The probability of getting a head on each occasion if a coin is tossed five times is equal to 1/2 x 1/2 x 1/2 x 1/2 x 1/2 (that is, 1/25) = 1/32 or one in thirty-two. The probability of getting a head on the fifth toss is 1/2. All other tosses are independent of the fifth toss. The probability of getting at least one head when tossing the coin 5 times: Since there are 32 possible combinations and only one of those combinations is all tails you could expect to toss a combination with a head 31/32 times. The probability is 0.96875.
There are five coins with a total value of 27 cents what is the probability that three of the coins are pennies?
Well, isn't that a happy little problem to solve! If there are five coins with a total value of 27 cents, and we want three of them to be pennies, that means the other two coins must add up to 6 cents. The probability of randomly selecting three pennies out of five coins is like painting a beautiful landscape - it's all about understanding the colors and creating a harmonious composition. So, the probability would be the number of ways to choose 3 pennies out of 5 divided by the total number of ways to choose 5 coins. Happy calculating!
What is the probability of getting at least one head if two coins were flipped?
Let put the question in an other way : obtaining at least one head is the contrary of obtaining two tails at the same time. The probability to obtain one tail with first coin is 1/2, the probability to obtain one tail with the other is also 1/2, so the probability to obtain one tail on each coin is 1/2x1/2 = 1/4 Thus the probability to obtain at least one head is 1-1/4=3/4
Collin has 4 coins that total 33p he is going to take one of his coins at radom what is the probability that it will be a 10p coin?
Well, Collin has a 10p coin and three other coins that don't matter in this scenario. So, the probability of him randomly picking the 10p coin is 1 out of 4, which simplifies to 25%. Good luck to Collin and his lucky coin!
