Big marbles = 45red 3/4 blue
Small marbles = 2/5 red 3/5 blue 24 more small blue mabrles than red marbles
What percentage of the marbles are big marbles
First of all lets working out the missing values:
Big Marbles, 45 red, 3/4 blue. If 45 red is 1/4, then 135 (45*3) is 3/4.
Big Marbles, 45 red, 135 blue = 180 in total
For the small marbles, we do some logical thinking:
If red is 2/5, and blue is 3/5. And blue has 24 more than red.
That means 24 = 1/5
So in total there are 120 small marbles (24*5)
There are 180 big marbles
We add these together, 120 + 180 = 300 marbles
180 / 300 = 0.6 = 60%
^ Divide the big marbles by the number of total marbles
60% of the marbles are big marbles

Where's the sample space? I need it to answer this question.
Answer:
7/10 or 70%.
Step-by-step explanation:
There is a total of 20 marbles in the bag.
There are 10 + 4 = 14 marbles which are not blue.
The required probability = 14/20
= 7/10.
Distribute the 5 into the polynomial to get 5a + 5b - a - b. Combine like terms to get 4a + 4b, your answer.
