Answer:
my best guess is answer choice c.
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


=> 
Answer:
feet tall
Step-by-step explanation:
Ajax is "5 and 1 fourth feet tall", which can be written as the mixed number
.
His sister is "3 eighths foot shorter", so she's 3/8 feet shorter than 5 1/4.
So, this is just a subtraction problem:

To solve this, we want to convert 5 1/4 into an improper fraction, which is:
. Now, we want to find a common denominator. In this case, that common denominator is 8, so
.
Finally, we subtract 3/8 from 42/8:
. So, Ajax's sister is 39/8 feet. Converting this into a mixed number, we have: 39/8 = 4
.
Therefore, Ajax's sister is
feet tall.
