What is the probability of spinning a blue and then a red or a yellow there are four colors on the board?
If there are four colors on a spinner, then the probability of spinning one particular color is 1 in 4, or 0.25. Also, the probability of spinning one of two particular colors is 2 in 4, or 0.5. Combining these two "unrelated" events simply requires multiplication. The probability, then, of spinning one particular color on one spin, and then spinning one of two particular colors on the next spin is (1 in 4) times (2 in 4), or 2 in 16, or 0.125.
What are the chances of spinning a 4 from 1 2 3 4 5 and 6?
On one spin, and assuming the spinner is fair, 1/6
What is the odd of landing on number 4 if you sun a spinner numbered1through4?
Assuming the numbers on the spinner are all given the same amount of space on the spinner, there is a 1:4 chance of spinning a 4. In other words, a 25% chance you spin a 4.
What is the probability of spinning less then 4 on a 5 section spinner or rolling a number less then 4 on a 6 sided number cube?
Assuming the spinner has sections numbered 1-5 then: Pr(Spin < 4) = 3/5 (= 0.6 or 60%) Pr(Roll > 4) = 3/6 = 1/2 (= 0.5 or 50%) Assuming both done together: Pr(spin < 4 or roll < 4) = Pr(spin < 4) + Pr(roll < 4) - Pr(spin < 4 and roll < 4 [at same time]) = 3/5 + 1/2 - 3/5 × 1/2 = 6/10 + 5/10 - 3/10 = 8/10 = 4/5 (= 0.8 or 80%) It can also be calculated out by working out the probability of not spinning less than 4 and not rolling less than 4 (at the same time), and then subtracting this from 1 (or 100%): Pr(spin < 4 or roll < 4) = 1 - Pr(spin ≥ 4 and roll ≥ 4) = 1 - (1 - 3/5) x (1 - 1/2) = 1 - 2/5 x 1/2 = 1 - 1/5 = 4/5 (= 0.8 or 80%)
There are 4 numbers the probability of spinning the number 3 is what?
The probability of spinning the number 3, or any number, is 1/4 or 0.25 since there is 4 numbers total.
