4 colours = 1 divided by 4 = 1 quarter per colour
red + blue = 1/4 +1/4 = 1/2
The probability is 0.625

To find the experimental probability of choosing a green marble, first calculate the total number of marbles: 7 red + 9 yellow + 14 green + 10 purple = 40 marbles. The probability of choosing a green marble is the number of green marbles divided by the total number of marbles, which is 14 green / 40 total = 0.35. Thus, the experimental probability of choosing a green marble is 0.35, or 35%.
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
If a five color spinner with equal sections of red blue green yellow and orange is spun six times, the probability of getting no reds in all six spins is 26.2%. The probability of no red on one spin is 4 out of 5, or 0.8 The probability of no red in six spins is 0.86.
the same as it is the first time 1/5
9 out of 12 for both of them put together 9:12 its on math.com I think
Assuming you want the probability FOR A SINGLE TRY, and you want the numbers in that exact order, the probability for each part (for instance, first = red; or second = green) is 1/4; therefore, the probability for the combination is (1/4) to the power 4.
3/5=g/30
The probability of choosing a blue marble is 5 in 15 or 1 in 3. The probability of then choosing a green marble is 5 in 14. (One is missing) Multiply the two probabilities and you get 5 in 42.(P = 0.1190... about 12%).
100%
Well, if the spinner has equal sections, and green is one of them, then statistically speaking, you would expect it to land on green about 100 times out of 600 spins. But hey, life's full of surprises, so don't bet your retirement savings on it!
