Answer:
7 to 8 hours
Step-by-step explanation:
1 * 4 = 4
5 / 6 * 4 = 20 / 6 = 3 2/6 or 3 1/3
4 + 3 1/3 = 7 1/3
Answer: there you go! I hope this helps!
Step-by-step explanation:
The PDF for the wait time (denoted by the random variable X) is
where λ = 1/75. We want to find Pr[X > 70 | X ≥ 40]. Pierre has already been waiting for 40 min, so if he waits another 30 min he will have waited for a total of 70 min.
By definition of conditional probability,
Pr[X > 70 | X ≥ 40] = Pr[X > 70 and X ≥ 40] / Pr[X ≥ 40]
If X > 70, then automatically X ≥ 40 is satisified, so the right side reduces to
Pr[X > 70 | X ≥ 40] = Pr[X > 70] / Pr[X ≥ 40]
Use the PDF or CDF to find the remaining probabilities. For instance, using the PDF,
Or, using the CDF,
Similarly, you'll find that Pr[X ≥ 40] ≈ 0.5866.
It follows that
Pr[X > 70 | X ≥ 40] ≈ 0.3932 / 0.5866 ≈ 0.6703
