Pat can make 8 outfits for each pair of pants. For all 8 shirts and the Never Back Down I Am An Arkansas Razorbacks Basketball Fan Now And Forever Shirt and I will buy this 4 pairs of pants, Pat can make 32 outfits. Higher pairs are not defined on the basis of the degrees of freedom. They are defined on the basis of contact between the two links of the kinematic pair. In a higher pair, the links have either line or point contact, and not a surface contact. The DOF depend purely on the pair itself. For example, the cam and follower have only a point contact usually has 2 DOF. Gear teeth mesh at a single point and there is only 1 DOF. A ball joint has a point contact but 3 DOF. Let’s say you have 1 shirt, 1 pair of pants and 4 hats, then how many combinations? The 4 hats make all the difference, so only 4 combinations. Now let’s say 1 shirt, *2* pairs of pants and 4 hats. For each pants, you have 4 hats, so that’s 8 combinations. That’s 2*4 For each of the 15 was of choosing pants Laly can chose 3 T-shirts out of her 5 T-shirts in 5C3 i.e. , 5C2 or 10 ways. For each of those choices he has a choice of 7 different shirts, so that gives him 4 times 7 = 28 different pant/shirt combinations. (I hope none of the pants are striped and none of the shirts have polka-dots).
