2 white counters and 1 black counter What is the probability that the counter will be black?
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. SM
A bag containing 4 green 6 black 7 white balls a ball is drawn at randomly probability of finding 2 red balls?
The probability is zero, because there are no red balls in the bag.
A bag contains 10 black marbles and 10 white marbles Five marbles are drawn and then replaced each time What is the probability of drawing five white marbles in a row?
It is (1/2)5 = 1/32
What is the equation used to determine probability?
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.
If there are 20 cars in a parking lot 7 are white 4 are blue 3 are tan 2 are red 2 are green 1 is black and 1 is yellowwhat is the probability for the color of the car that will drive away next?
35% white,20%blue,15%tan,10% red and green and 5% black and yellow
What are the odds in favor of choosing a white marble from a bag containing 3 black marbles 4 green marbles and 6 white marbles?
The probability of drawing a white marble is .46
A bag contain 4 green 6 black 7 white balls a ball is drawn at random what is the probability that it is a green or a black ball?
This is a law of addition probability which states that the probability of A or B equals the probability of A plus the probability of B minus the probability of A and B. Written in mathematical terms, the equation is: P(AorB) = P(A) + P(B) - P(AnB) where P(AnB) = 0 (since you can not pull out a green and black ball at the same time). Let P(A) = Probability of drawing the green ball & let P(B) = Probability of drawing the black ball. Total outcomes is 17. So, P(A) = 4/17 & P(B) = 6/17. Therefore P(green or black) = 4/17 + 6/17 = 10/17.
An urn with 8 red chips a green chips and 2 white chips what's the probability of getting a white chip on the first draw?
The odds of drawing a white chip are 18,18181818%. Or 2 chances on 11
A marble is drawn at random first from a jar containing four black and four white marbles and then from a jar containing six black and two white marbles What is the probability of drawing two black?
It is (4/8)*(6/8) = 3/8
What is monochrome drawing?
A drawing done in only one color. a black and white drawing is considered monochrome, as the "color" would be black on a white tapestry.
What is the probability of drawing a marble that is not white?
It depends on how many marbles of each colour you have....
Whats balck and white black and white black and white and green?
Black and white black and white black and white and green is a ragga son.
If a box contains 4 red marbles seven white and 5 blue and two marbles are drawn one at a time with replacement What is the probability that both marbles are white?
Since the box contains 16 marbles, seven of them white, then the probability of drawing one white marble is 7/16. If you replace the marble and draw again, the probability of drawing another white marble is still 7/16. The net probability of drawing two white marbles, while replacing the first, is 49/256.
2 white counters and 1 black counter What is the probability that the counter will be black?
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. SM
What is the probability of drawing 1 green then 1 blue marble from a bag with 5 blue marbles 5 red marbles 3 green marbles 2 white marbles?
hypergeom. f(1;13,3,1) * f(1;12,5,1)
Calculate the probability that an offspring will be black in the cross in punnet square b what is the probability it will be white?
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.
What is probability that you pick 3 white balls if you have 3 white balls 1 red ball and 2 green balls?
The probability that you pick 3 white balls is 0.05 or 5%.----------------------------------------------------------------------------------------------------EXPLANATIONThe probability of first drawing a white ball is: P(W1) =3/6.The probability of drawing a white ball given the event that you already draw awhite ball in the first draw and not replacing it back is: P(W2│W1) =2/5.The probability of drawing a white ball on the third draw given the event that awhite ball was drawn in the first and in the second draw is: P(W3│(W1UW2)) =1/4Now, the probability of drawing 3 white balls one by one with out replacement(taking all 3 balls at a time gets the same analysis and result) is:P(W1UW2UW3) =P(W1)∙P(W2│W1)∙P(W3│(W1UW2)) =(3/6)∙(2/5)∙(1/4) =1/20=0.05 =5%.
