Explanation:

P (picking either a black or a queen) = 1 – P (picking neither a black nor a queen)

Total cards which are either black or queen = 28.

∴ P (picking neither a black nor a queen) = 24/52 × 23/51 = 46/221

∴ P (picking either a black or a queen) = 1 – 46/221 = 175/221

Hence, option (a).
