How do you find the probability of a spinner?
You find out how many choices there are in a spinner and then you take what it wants you to find the probability of and tur it into a fraction For example: You have a spinner with 4 triangles in it....2 are red and 2 are green,What is the probability of landing on a green triangle 2 out of 4
A spinner has 5 equal sections There are 3 green sections and 2 yellow sections The spinner is spun 30 times Which proportion can be used to find the number of times that the spinner lands on green?
3/5=g/30
If you toss a coin 1000 times and find that it comes up head 532 times what is the probability of getting a tail?
The probability is still 50%
A pair of fair dice is tossed 3 times find the probability a seven appears 3 times?
The probability that the sum is seven all three times is 1/216.
How do you find the experimental probability that a particular result will occur?
You carry out the experiment a large number of times. Count the number of times it was carried out (n). Count the number of times in which the particular outcome occurred (x). Then, the experimental probability for that even is x/n.

If the spinner is spun 20 times how many times would you expect to land on 3?
To determine how many times you would expect to land on 3 after spinning the spinner 20 times, you need to know the probability of landing on 3 in a single spin. If the spinner has an equal number of sections, you can find the probability by dividing the number of sections that include 3 by the total number of sections. Multiply that probability by 20 to get the expected number of times landing on 3. For example, if the spinner has 4 equal sections, the expected number would be (20 \times \frac{1}{4} = 5).
You spin the pointer on the spinner. find the probability the pointer will land on 3?
To find the probability of the pointer landing on 3, you need to know the total number of equal sections on the spinner. If the spinner has ( n ) sections, and one of them is labeled 3, the probability is calculated as ( \frac{1}{n} ). For example, if there are 8 sections, the probability would be ( \frac{1}{8} ). Without knowing the total number of sections, the exact probability cannot be determined.

What is the probability that you will spin a 4 and roll a 4?
Assuming each possible number on a spinner has the same probability and an unbiased die is being rolled, the answer depends on how many numbers are on the spinner, and how many times the number 4 appears on each.To find the probability, workout the probability of spinning a 4 on the spinner and the probability of rolling a 4 on the die; then as spinning the spinner has no effect on rolling the die, they are independent events and to get the probability of both happening multiply them together.The probability of success is the number of successful outcomes divided by the total number of outcomes, giving:Probability(spinning a 4) = how_many_4s_are_on_the_spinner / how_many_numbers_are_on_the_spinnerProbability(rolling a 4) = how_many_4s_are_on_the_die / how_many_numbers_are_on_the_dieProbability(spinning a 4 and rolling a 4) = Probability(spinning a 4) × Probability(rolling a 4)Examples:an octagonal spinner with the numbers 1-4 on it each twice and a tetrahedral die (as used in D&D games) with the numbers 1-4 on it→ pr(spin 4 & roll 4) = 2/8 × 1/4 = 1/16a decagonal spinner with the numbers 0-9 and a tetrahedral die with the numbers 0-3 on it→ pr(spin 4 & roll 4) = 1/10 × 0/4 = 0a decagonal spinner with the numbers 0-9 and a standard die with the numbers 1-6 on it→ pr(spin 4 & roll 4) = 1/10 × 1/6 =1/60
If a spinner with 4 equal sections labeled A B C and D is twice what is the probability of A twice in a row?
The probability of landing on A in one spin is ( \frac{1}{4} ). To find the probability of landing on A twice in a row, you multiply the probabilities of each independent event: ( \frac{1}{4} \times \frac{1}{4} = \frac{1}{16} ). Therefore, the probability of landing on A twice in a row is ( \frac{1}{16} ).
How do you find experimental-probability?
To find the experimental probability of an event you carry out an experiment or trial a very large number of times. The experimental probability is the proportion of these in which the event occurs.
What is the probability of spinning a number greater than 5 on a spinner numbered 1 to 8 and tossing a tail on a coin?
To find the probability of spinning a number greater than 5 on a spinner numbered 1 to 8, we note that the numbers greater than 5 are 6, 7, and 8, giving us 3 favorable outcomes out of 8 total outcomes. Thus, the probability of this event is 3/8. For the coin toss, the probability of getting a tail is 1/2. The combined probability of both events occurring is (3/8) × (1/2) = 3/16.

Explain how using a spinner would help find the experimental probability that a soccer player who makes 75 percent of his penalty kicks will score a goal on a penalty kick?
Get the spinner and have 4 sections, 3 with score and 1 with miss. Whichever one it lands on is the outcome. However, this is only purely theoretical as football/ soccer is played on grass and not with a spinner.

What is the possibility that you will get heads four times in a row when flipping a fair coin?
The probability of getting heads on a single coin flip is 0.5. To find the probability of getting heads four times in a row, you multiply the probability of getting heads for each flip: (0.5 \times 0.5 \times 0.5 \times 0.5 = 0.5^4 = 0.0625). Thus, the probability of flipping heads four times in a row is 6.25%.
