In a bag containing 6 purple marbles 19 green marbles 5 blue marbles 19 yellow marbles and 17 red marbles what is the probability of pulling out a yellow marble?
Total number of marbles in the bag = 6 + 19 + 5 + 19 + 17 = 66Number of yellow ones = 19If drawing perfectly randomly, then the probability of pulling a yellow one = 19/66 = 28.8% (rounded)
What is the probability of selecting 4 red or 5blue marbles?
The probability of selecting 4 red marbles or 5 blue marbles depends on how many marbles there are altogether, and how many of the total number of marbles are red and how many are blue.
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.
What is the probability of pulling of pulling out a blue marble returning it to the jar and then pulling out a green marble?
The probability is B*G/(B+G+R)^2where B = number of Blue marbles G = number of Green marbles and R = number of marbles of other colours.
There are 3 red marbles 7 blue marbles 6 green marbles and 4 black marbles in a bag a marble is randomly selected from the bag the number one fifth represents the probability of selecting what color?
a black one
What is the probability of drawing two pink marbles if the first one is placed back in the bag before the second draw?
it depends on the total number of marbles you have!

A bag contains 3 red marbles 5 blue marbles 8 yellow marbles and 4 black marbles what is the theoretical probability of randomly picking each color marble?
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.

The probability is B*G/(B+G+R)^2where B = number of Blue marbles G = number of Green marbles and R = number of marbles of other colours.

a black one
What is the probability of rolling a number greater than 4 and then pulling a red marble out of the bag without looking?
The probability of rolling a number greater than 4 is 2/6, that is, 1/3. For the probability of pulling out a red marble, more data has to be known. Just put the number of red marbles in the numerator, the total number of marbles in the denominator. Finally, multiply the two probabilities.
What is the probability of not drawing a heart?
Number of cards in a deck = 52 Number of cards that are heart = 13 Therefore number of cards that are not heart = 52-13 = 39 Probability of not drawing a heart = 39/52 or 3/4
What is the probability of drawing a red card and a number 7?
your ugly face
What is the probability of drawing 2 hearts and then a spade in that order from a deck of 52 cards?
In order to determine the probability of drawing 2 hearts and then a spade, in that order, from a deck of 52 cards, start by considering the first card. The probability of drawing a heart is 1 in 4. Since you have now reduced the number of hearts and the number of cards in the deck by one, the probability of drawing another heart is 4 in 17. Since you have further reduced the number of cards by one, the probability of drawing a spade is 13 in 50. Multiply these probabilities together, (1/4) (4/17) (13/50), and you get about 0.0153, or about 153 in 10000.
What is the probability of drawing a heart?
! in 4, as the four suits have an equal number of cards.
