Box A: 25 slips (19 marked Re 1, 6 marked Rs 5). Box B: 50 slips (45 marked Re 1, 5 marked Rs 13). Slips are mixed and one slip is drawn. Probability it is marked other than Re 1?
\(\dfrac{11}{75}\)
Step 1: First, find the total number of slips in each box.
Total slips = 25 + 50 = 75.
Step 2: Now find how many slips are marked other than Re 1 in each box.
Step 3: Add them together.
Number of slips other than Re 1 = 6 (from Box A) + 5 (from Box B) = 11.
Step 4: Probability formula is:
\( P(E) = \dfrac{\text{Favourable outcomes}}{\text{Total outcomes}} \)
Step 5: Put the values in the formula.
\( P(\text{slip not Re 1}) = \dfrac{11}{75} \)
Final Answer: The probability that the slip is marked other than Re 1 is \(\dfrac{11}{75}\).
