it depends on how many other colors there are.
1/3
one out of six
2/3
The probability of landing on black twice on a spinner with white, black, and striped sections is (1/3)^2 = 1/9. This is because there is a 1/3 chance of landing on black on each spin, and the spins are independent events.
1/16
The answer depends on the shape of the spinner.
The experimental probability, by definition, can only be determined after you have carried out the experiment!
If a black hole has spin, it will spin forever.
The probability is one half.
The probability of getting a diamond and a black seven is zero. Diamonds are red.
It is the theory of what might happen, but not actually what happens. In theory, if you spin a coin 100 times, it should come up on heads 50 times, as there is a 1 in 2 chance of you getting heads on each spin. If you actually do spin a coin 100 times, the total of heads is the experimental probability, so what you actually get. That may not be 50. It is likely to be close to 50 though.
Probability of not drawing a black six from a deck of cards = 1 - probability of drawing a black 6 = 1 - 2/52 = 50/52 = 25/26.
