20% Total marbles = 35 + 85 + 30 = 150 Yellow marbles = 30 Percentage yellow marbles = number_of_yellow / total_number x 100 % = (30 / 150) x 100 % = 1/5 x 100 % = 20%
a+b=23 b=a+3 a+b a+(a+3)=23 a+a=23-3 2a=20 a=10 green marbles=10 blue marbles =23-10 =13
Because 1/3 are blue and 1/2 are red and the rest are green we can calculate that 1/6 of the marbles are green. 1/3 = 2/6 1/2 = 3/6 2/6 + 3/6 = 5/6 which leaves 1/6 green. Since there are 7 green marbles we know there must be 7 x 6 total. The answer is 42 marbles.
He will have 13 blue marbles and 10 green marbles.
He has 10 green marbles.
10 Green marbles, 13 Blue marbles.
The theoretical probability of randomly drawing a green marble can be calculated by dividing the number of green marbles by the total number of marbles in the bag. In this case, there are 12 green marbles out of a total of 5 red marbles + 8 blue marbles + 12 green marbles, which is 25 marbles in total. Therefore, the theoretical probability of drawing a green marble is 12/25 or 48%.

To determine the probability of getting a green marble, you need to know the total number of marbles and the number of green marbles specifically. The probability is calculated by dividing the number of green marbles by the total number of marbles. For example, if there are 5 green marbles out of 20 total marbles, the probability would be 5/20, which simplifies to 1/4 or 25%.
it depends how many blue marbles there are and how many marbles total.
56 marbles (TOTAL)
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.
Number of marbles in total = 90 Fraction of marbles are blue = five-ninth Number of blue marbles = five-ninth of ninety = 50 So, the answer is 50 blue marbles.

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.
