(12:2,1,2,3+1+3) A box contains 10 identical markers (except in colors): 5 black, 3 blue and 2 red. THREE different markers are selected. Find the probability of selecting at least one red marker. amb b. Find the probability of getting a blue marker first, then 2 black markers. c. Find the probability of getting one black marker. IV d. Create a probability distribution of the number of black markers selected. Then extend to compute the expectation and standard deviation of the number of black markers selected
