Probability 7th class maths?
two dice are thrown once. write all the possible outcomes. find the probability of getting: (i) a total of 12 (ii) a total of 3 (iii) a total of 8
When 2 dice are thrown what is the probability that a total of 9 will not appear?
1/36
What is the probability of getting a number greater then 5 on a spinner?
The probability is(the total number of numbers on the spinner minus 5)/(the total number of numbers on the spinner)Another way to express the same probability is1 - 5/(the total number of numbers on the spinner)
What is the probability of getting a green marble?
To determine the probability of getting a green marble, you need to know the total number of marbles and the number of green marbles specifically. The probability is calculated by dividing the number of green marbles by the total number of marbles. For example, if there are 5 green marbles out of 20 total marbles, the probability would be 5/20, which simplifies to 1/4 or 25%.
If you were to flip a coin 6 times what is the probability of you getting at least four heads?
To calculate the probability of getting at least four heads when flipping a coin six times, we can use the binomial probability formula. The total number of outcomes for six flips is (2^6 = 64). The probabilities for getting exactly four, five, and six heads can be calculated using the binomial formula, and their sum gives the total probability of getting at least four heads. This results in a probability of approximately 0.65625, or 65.625%.

What is the probability of throwing the dice and getting a total of 5 on the first throw and getting a total of 10 on the second throw?
You have not given any information about the shape and numbering of the dice nor how many are thrown each time. Without that information it is not possible to answer the question.
When two dice are rolled what is the probability of getting a total of 27?
If they are normal dice, the probability is 0.
What is the probability of getting a total 2 when rolloing two dice?
It is 1/36.
What is the probability of getting a number greater then 5 on a spinner?
The probability is(the total number of numbers on the spinner minus 5)/(the total number of numbers on the spinner)Another way to express the same probability is1 - 5/(the total number of numbers on the spinner)
What is a probability of getting a sum Nine when two dice are thrown?
Throwing two dice, there are a total of 36 combinations (1-1, 1-2, 1-3, etc.), each of which has the same probability. Of these, the following give a sum of nine: 3-6, 4-5, 5-4, 6-3. That makes four favorable cases, or a probability of 4/36.

How do you find the prbability of getting something?
There a formula: Probability = No. of Cases in favour / Total no. of cases
What is the probability of getting a diamond in a deck of 52 cards?
-- Total number of cards = 52.-- Number of diamonds = 13 .-- Probability of success = (# of successes)/(# of total possibilities) = 13/52 = 25% .
How do probability work?
Probability are the odds of something happening but has multiple answers. Such as probability of getting a 5 in a fair dice would be 1 out of 6 because there are 6 numbers on a dice altogether, and ONE chance of getting a 5 from the total of 6. Therefore, the probability of getting a 5 or any number from a dice would be 1/6.
What is the probability of getting a 2 on a six sided dice?
The probability of getting a 2 on a six sided die is 1/6. The probability of rolling a 5 is 1/6 The probability that any of the six numbers will come up is 1/6. Probability is found by "the number of ways of getting the favorable event/the total number of possibilities". Since there is only one number 2 on a a die, then there is only one way to get the favorable event. The total number of sides on a die is 6, so there are six different possibilities total that can come up. So, probability of rolling a 2 is 1/6.
