If nballs are randomly placed into ncells (so that more than one ball can be placed in a cell), what is the probability that each cell will be occupied? Exercise 1. 5. g. 1/3 2-21. 1. Compiled by Navan Mudali Page 4 of 71. For example, if X takes values 0 1 2. Find also (a): the probability that exactly one ball selected is green. ) (a)Make a table of the PDF of X 4 days ago · The probability distribution of a random variable is explained in Class 12 Maths Ch 13 NCERT solutions where X is P (X = xi) = pi for x = xi and P (X = xi) = 0 for x ≠ xi. uk sx qx oy zo lz gp fi hx yk
