- A committee has seven members. There are three members that currently serve as the board's chairman, ranking member, and treasurer. Each member is equally likely to serve in any of the positions. Three members are randomly selected and assigned to be the new chairman, ranking member, and treasurer. What is the probability of randomly selecting the three members who currently hold the positions of chairman, ranking member, and treasurer and reassigning them to their current positions? The probability is. (Round to four decimal places as needed.) ←21. A box contains five red, two white, and three green marbles. If a marble is selected at random, find these probabilities. b. That it is green. a. That it is red. d. That it is not green. c. That it is not red.There are two white balls in box B1, two red balls in box B2, two white and two red balls in box B3, and three white and one red balls in box B4. The probability of choosing boxes B1, B2, B3 or B4 is given as 1/2, 1/4, 1/8 and 1/8 respectively. One of the boxes is chosen at random and a ball is drawn at random from the selected box. What is the probability that the selected ball comes from box B3 under the condition that it is white?
