(iv) The letters available without E are V, R, G, N. We need to select 3 letters with exactly 1 R. Possible selections are RVG, RVN, RGN. Thus, there are 3 ways.

(v) Without E, the letters are V, R, G, N. We need to select 3 letters:

• No Rs: Only one way, VGN.
• 2 Rs: Choose 1 more letter from V, G, N. Possible selections are RRV, RRG, RRN, which is 3 ways.

\(Total selections without E: 1 (no Rs) + 3 (2 Rs) = 4 ways.\)
