Answer: smaller
Ultraviolet radiation has broad range of wavelengths, higher
number means greater risk of exposure to UV rays that can be dangerous to skin
cells. Sunlight is the main source of electromagnetic radiation and it is
transmitted in different wavelengths known as electromagnetic spectrum. This spectrum
is divided into several regions in order of decreasing wavelength and increasing
energy and frequency. UV radiation has frequency and energy that is higher than purple
light or violet radiation and the wavelength of ultraviolet radiation
is smaller than violet radiation.

C and D
Explanation:
A uniform probability model is a probabilistic model characterized by a uniform probability density function, or uniform distribution.
In common language, a uniform probability distribution means that all possible outcomes in the probability space have the same probability of occurrence.
So:
- A fair toss of coin every possible outcome (H,T) has probability 0.5. It is modeled by by a uniform discrete distribution.
- Randomly selected answer to an MCQ with four options would have probability of success 0.25 for every MCQ. It is modeled by by a uniform discrete distribution.
- Spinning a spinner with sections that are different sizes, each section would have different probabilities proportional to the coverage area on the. It is modeled by a non-uniform discrete distribution
- Pulling a red marble out of a bag with 6 red marbles, 3 green marbles, and 1 yellow marble. Each successive time a red marble is drawn the probability decreases. Hence, non uniform distribution.
- Spinning a spinner on which all sections are the same size. Each section would have similar probabilities proportional to the coverage area on the. It is modeled by a uniform discrete distribution .
