Answer:
Probability = 37.5%
Step-by-step explanation:
Prob (Race fast) = 10%, Prob (Slight Fast) = 40%, Prob (Normal Car) = 50%
Prob (Red Car) = 70% of race fast cars, & 45% of slight fast cars, & 30% of Normal cars, & = (70% x 10%) + (45% x 40%) + (30% x 50%) = 7% + 18% + 15% = 40%
Prob (Normal & Red Car) = 30% of 50% = 15%
Prob (Red car I Normal car) = Prob (Red & Normal Car I Normal Car) = 15% / 40% = 37.5%

Answer:
0.167
Step-by-step explanation:
Arrival time of the bus = 30 minutes
We have to find the probability of waiting between 25 to 30 minutes.
From this we have that,
a = 0
b = 30
The solution can be expressed as;
P(25<x<30) = (30 - 25) / (30 - 0)
P(25<x<30) = 5/30
P(25<x<30) = 0.167
0.167 is the probability of waiting between 25 minutes and 30 minutes.
