Whereever we want a specific specification part , we remove the no. of combinations related to that part. So, i have used the same
funda to calculate the below:
49. no. of diff combos possible = 4*2*2*1*3*3*3 = 432
50. no of combos possible with a 2 TB hard drive = 4*1*2*1*3*3*3 = 216
51. no. of such combos = 1*2*2*1*3*1*3 = 36
52. no. of such combos = 2*2*1*3*3*3 = 108
53. no. of such combos = 2*1*3*3 = 18
54. no. of such combos = 4*2*2*1*3*3*2 = 288
