A circuit board requires 9 different Integrated Circuits (IC). There are 4 vendors who manufacture these 9 kinds of ICs. They are Texas Instruments (TI), National Instruments (NI), Motorola (M), and Qualcomm (Q). Khloe orders 9 ICs from the 4 vendors at random.
Find the probability of the following events (explain how you get to the solution):
• The circuit board has at least one IC from TI, at least one IC from M and at least one IC from Q.
• The circuit board has no ICs from TI and NI.
