The table above shows the number of limes and apples of the same size in a bag. if two of the fruits are picked at random, without replacement, find the probability that:
a. both are good limes
b. both are bad fruits
c. one is a good apple and the other is a bad lime

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
