Step 1: Understanding Colour Mixing.
When yellow and red, two primary colours, are mixed together, they form orange, a secondary colour. This is a basic principle of subtractive colour mixing, where the combination of these two primary colours produces a new colour.
Step 2: Verifying the Options.
- Option (1): Yellow mixed with red forms orange, making this the correct answer.
- Option (2): Brown is not produced by mixing yellow and red; it typically requires a combination of red, blue, and yellow.
- Option (3): Paddy green is a mix of blue and yellow, not yellow and red.
- Option (4): Sky blue is a shade of blue, not produced by mixing yellow and red.
Conclusion:
Therefore, the correct answer is (1) Orange.
Find the unknown frequency if 24 is the median of the following frequency distribution:
\[\begin{array}{|c|c|c|c|c|c|} \hline \text{Class-interval} & 0-10 & 10-20 & 20-30 & 30-40 & 40-50 \\ \hline \text{Frequency} & 5 & 25 & 25 & \text{$p$} & 7 \\ \hline \end{array}\]
