The sum of the zeros of the polynomial
5x² + (5p − 1)x − (2p + 5) is the same as one fourth of their product. Find the value of p.
A box contains 6 white, 2 black and 3 red balls. If a ball is drawn at random, what is the probability that it will not be white?
\( \frac{5}{6} \)
\( \frac{6}{5} \)
\( \frac{5}{11} \)
\( \frac{6}{11} \)
