Answer: Our required probability is 0.618.
Step-by-step explanation:
Since we have given that
Probability of all drivers were involved in a car accident last year = 66%
Number of drivers = 10
Number of drivers involved in a car accident = 3
So, probability of drivers involved in car accident is given by
Probability of getting 3 or more who were involved in a car accident is given by
P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)
Here,
So, our equation becomes
P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)
Hence, our required probability is 0.618.
Answer:
Angle PAB is a right angle.
Step-by-step explanation:
Angle PAB is a right angle. In circles, tangent lines are always perpendicular to radii.
The time taken to reach train from Zurich to Paris is 8 hours 52 minutes.
Step-by-step explanation:
The given is,
Train leaves Zurich at 22:40
Train arrives Paris at 07:32
Step:1
Time taken to reach from zurich to paris,
= Train leaves at Zurich - Train arrives at Paris
= 22:40 - 07:32
= 8.52 hours
Step:2
Time taken by train to reach from zurich to paris in minutes,
= 8.52 hours
= 4831 minutes 12 secs
Result:
The time taken to reach train from Zurich to Paris is 8 hours 52 minutes, if a train leaves Zurich at 2240 and arrives in Paris at 0732.
Answer: .3 as a fraction is 3/10
3/10 and .3 as a percent is 30%
It is said that 85% of the students liked reading mystery stories. This means the remaining 15% don't like to read these stories. If there are 30 students belonging to the second category, then the number of students who liked reading mystery stories is (30/0.15)*0.85 equal to 170 students out of 200 students.
