Natalie performed a probability experiment that involves multinomial distribution. She put the colored chips that she prepared in a jar. The jar now contains 3 red chips, 2 violet chips, 2 blue chips, and 4 black chips. Blindfolded, she selects one chip at random. She records the color after every draw and put the chip back in the jar. She repeats it for 30 times. See attached file for the table. Given that there are 5 trials, a) Determine the probability that 2 red chips, 2 black chips, and 1 violet chip are picked. b) Determine the probability that 4 black chips and 1 violet chip are picked. c) Determine the probability that 2 black, 1 red, 1 blue, and 1 violet chip are picked
