Each year, 64 golfers participate in a golf tournament. The golfers play in groups of 4 . How many groups of 4 golfers are possible? (See Example 5 .)
Find the number of ways you can arrange (a) all of the letters and (b) 2 of the letters in the given word. (See Example 1.) $$\mathrm{TRY}$$
Write an equation that relates \(_{n} P_{r}\) and \(_{n} C_{r}\) . Then use your equation to find and interpret the value of \(\frac{_{182} P_{4}}{_{182} C_{4}}\)
Solve the equation. Check your solution. $$\frac{1}{4} x+0.5 x=1.5$$
Count the possible combinations of \(r\) letters chosen from the given list. (See Example 4 .) $$\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D} ; r=3$$
