a. 10%
b. 3%
c. 20%
d. 30%

option d. 30%

Step-by-step explanation:

Data provided in the question:

Now,

The probability density function of the uniform distribution is given as:

Therefore,

The required probability will be

or

= 0.3 × 100%

= 30%

Hence,

The answer is option d. 30%

i got 10.28 but that rounds up to 10.3
