Step 1
Given:
The range of uniform distribution is between 5 to 7 years.
The objective is to find the probability of randomly chosen student who will stay at most 6 years.
Step 2 The formula to find the required probability is,
$$\displaystyle{P}{\left({X}\leq{6}\right)}={\frac{{{x}-{a}}}{{{b}-{a}}}}$$
Here, a, b stands for lower limit and upper limit.
From the given data, $$\displaystyle{a}={5}$$ and $$\displaystyle{b}={7}$$
Now substitute the obtained values in the formula of probability.
$$\displaystyle{P}{\left({X}\leq{6}\right)}={\frac{{{6}-{5}}}{{{7}-{5}}}}$$
$$\displaystyle={\frac{{{1}}}{{{2}}}}$$
$$\displaystyle={0.5}$$
Hence, the probability of randomly chosen student who will stay at most 6 years is 0.5.
