Note: Hey, since multiple questions are posted, we will answer first question (question 20) for you. If you want any specific question to be answered, then please submit that question only or specify the question number in your message.20) A container contain 4 red, 3whitr and 5 yellow marbles Total number of marbles is 4+3+5 =12. The number of white marbles is 3. It is given that first marble is white and throws it away. Thus, the second white marble can be selected from the remaining 11 marbles in 2 different ways. The probability that the second marble is W, if first marble is W is as follows: Probability=211 =0.1818
