Question 92936
A list of numbers consists of p positive and n negative numbers. If a number is picked at random from this list, the probability that the number is positive is 3/5. What is the value of n/p?
PROBABILITY OF PICKING A POSITIVE NUMBER = P/(N+P)=3/5
HENCE
P/{(N+P)-P}= P/N =3/(5-3)=3/2
 N/P = 2/3
