1/2
Because there is 2 white counter and 1 black and there is a chance you will get white.
But a probability getting white is that there is 2 white counters.

A probability meter is a visual aid to communicate the meaning of probabilities. It is usually a white and black circles that can be rotated to show segments of the circle corresponding to the probability; e.g. a one quarter segment of the circle black represents a probability of 25%.
50% from both so its half!
The probability of a simple event is the number of ways to succeed over the total possibilities. So, there are three white balls, and ten balls total. So: P(white) = 3/10
Number of possibilities for one category / Total of all possibilities. For example, if I had a bag of marbles where there are three white marbles and two black marbles. The probability of pulling out a white marble is how many white marbles are in the bag which is: three. But the total of things you can draw out of the bag can either be one of the three white marbles or one of the two black marbles. 3 white marbles+ 2 Black marbles= five marbles. Possibility is 3/5 for drawing a white marble.
The probability is zero, because there are no red balls in the bag.
No 'cause there are black AND white counters innir? ^yes but it is a fight between white and black. ^It is, cause white always starts first
In a monohybrid cross with black as dominant (B) and white as recessive (b), the probability of an offspring being black is 75% (3/4) and the probability of being white is 25% (1/4) according to the Punnett square ratios.
probability of hitting a white key 7/12, probability of hitting a black key 5/12. Assuming all key have an equal possibility of being hit.
A number of laws and rules evolved over the years separating black and white people. Then a well researched book, An American Dilemma, claimed that segregation prevented equality. College students read it and became determined to end segregation. Black people were not allowed to sit at the same lunch counters as white people. Black students wanting equality knew they had to start somewhere and decided to attack that rule. They started by sitting at the white lunch counter.
That would be based upon the remainder of the probability it could be anything else, depending upon all of the other choices (red, white, yellow, Caucasian...). For example, if there is a 99 percent chance it's white, and the only two choices are white or black, and there are no external constraints that prevent it from being less than random, there would be a 1 percent probability it would be black.
move one unshaded counter to the 3rd dish that only has two circles in it. You have 12 total counters ..9 are shaded 3 are not. fractions would be 9/12 and 3/4 (9 counters are shaded out of 12 total counters) and (3 dishes out of 4 are shaded)

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.
1/6. There are 6 possible combinations of 2 you could pull out of the washer (red&black, red&white, red&gray, black&white, black&gray, white&gray), and red and black is one of them.
