Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The number of green marbles is 
The number of red marbles is 
The number of red marbles is 
Generally the total number of marbles is mathematically represented as
Generally total number of marbles that are not red is
=> 
=> 
The probability of the first ball not being red is mathematically represented as
=> 
The probability of the second ball not being red is mathematically represented as
=> 
(the subtraction is because the marbles where selected without replacement )
=> 
The probability that the first two balls is not red is mathematically represented as
=> 
=> 
The probability of the third ball being red is mathematically represented as
(the subtraction is because the marbles where selected without replacement )
=> 
Generally the probability of the first two marble not being red and the third marble being red is mathematically represented as
=>
<span>1/8 + 2(1/2m + 5) = 1/4m + 7 would equal m=-25/6</span>
15, 18, 21
i don't know the other one, sorry
Answer: There are 32 pints of first type and 128 pints of second type in mixture.
Step-by-step explanation:
Since we have given that
Percentage of pure fruit juice in first type = 60%
Percentage of pure fruit juice in second type = 85%
Percentage of pure fruit juice in mixture = 80%
We will use "Mixture and Allegation" to find the ratio of first and second type in mixture:
First type Second type
60% 85%
80%
------------------------------------------------------------------------
85-80 : 80-60
5% : 20%
1 : 4
so, the ratio of first and second type is 1:4.
Total number of pints of mixture = 160
Number of pints of mixture of first type in mixture is given by
Number of pints of mixture of second type in mixture is given by
Hence, there are 32 pints of first type and 128 pints of second type in mixture.
