Answer: 0.625
Step-by-step explanation:
Given : The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed with interval= [0 minutes, 6 minutes]
The probability density function :-

The interval of required event = [2.25 seconds, 6 seconds]
Now, the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes is given by :-

Hence, the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes = 0.625
18/12=21/Y | :3
6/12=7/Y
Y= 7*12/6
Y=7*12/6=14
18/12=X/10 | :2
X= 18*10/12
X=3*10/2
X=15
Answer:
9 and 11
Step-by-step explanation:
0.18 / (0.18 + 0.12 + 0.54) =
0.18 / 0.84 =
0.2143 <=
