Correct Answer - Option 1 : 3/7

**Given :**

A bag has four cuboids and three cubes

**Concept used :**

Probability of outcome = Total favourable outcomes/Total possible outcomes

**Calculations :**

Chances of cuboid to come = 4

Chances of cube to come = 3

Total possible outcomes = 3 + 4 = 7

Probability of getting 1 cube = 3/7

**∴ Option 1 will be the correct answer.**
