Answer:
3/7
Step-by-step explanation:
The probability of at least is 1 - the probability of at most
P(at least x) = 1 - P(at most x)
The given is:
1. A bus arrives at a bus stop every 35 minutes
2. You arrive at the bus stop at a random time
3. You will have to wait at least 20 minutes for the bus
∵ The bus arrives at a bus stop every 35 minutes
∵ You arrive at the bus stop at a random time
∵ You will wait at most for 20 minutes for the bus
∴ P(at most 20 minutes) =
∵ P(at least 20 minutes) = 1 - P(at most 20 minutes)
∴ P(at least 20 minutes) = 1 -
∴ P(at least 20 minutes) =
- Simplify the fraction by divide up and down by 5 and you will get your answer!

Answer:
Step-by-step explanation:
Given
First, we need to list the multiples of 5
Then, multiples of 3
Next, is to list out the common elements in both
The required probability is then calculated as thus:
The answer is
3x-4y=-24
y=mx+b
-4y=-3x-24
y=(3/4)x+(-24/-4)
y=(3/4)x+6
slope m=3/4
y =6
Two equivalent ratios for 30 to 6 can be 15 to 3 or 45 to 9
F(2)=2(3*2)+1
f(2)=2(6)+1
=13
answer is 13
