The probability of drawing a violet marble on the first draw is 5/11. Having drawn violet on the first draw, there are now 4 violet marbles left and a total of 10 marbles. So, the probability of violet on the second draw is 4/10.
All the exponents in the algebraic expression must be non-negative integers in order for the algebraic expression to be a polynomial. As a general rule of thumb if an algebraic expression has a radical in it then it isn't a polynomial
an improper fraction is any fraction with a numerator bigger then the denominator.
a mixed number is the "proper" version of an improper fraction.
the fraction 11/4 as a mixed number is 2 and 3/4.
to make an improper fraction a mixed number, find out how many times the denominator goes into the numerator. whatever you have left that didn't make 1 whole, turns into the fraction .
