Answer :
Answer:
0.269
Step-by-step explanation:
Data provided in the question:
Probability density function f(t) = [tex]\frac{1}{52}[/tex]
where, 0 ≤ t ≤ 52
Now,
The probability that we will wait at least 38 minutes = Probability we will wait more than 38 minutes
thus,
integrating the Probability density function from 38 minutes to maximum time 52 minutes
therefore,
P = [tex]\int\limits^{52}_{38} {f(t)} \, dx = \int\limits^{52}_{38} {\frac{1}{52}} \, dx[/tex]
or
P = [tex]\frac{1}{52}[t]_{38}^{52}[/tex]
or
P = [tex]\frac{1}{52}[52-38]}[/tex]
or
P = 0.269
