In conditional probability, the notation P(A | B) is read:
1 answer:
The probability of a student taking the bus given that the student is a sophomore is 0.83
The complete question is attached with the answer below:-
<h3 /><h3>What is probability?</h3>Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Given that:
- P(Walk to school | Sophomore) = 3 /(2 + 25 + 3) = 0.1
- To calculate the probability of a student taking the bus given that the student is a sophomore, we make use of:
- P(Take the bus | Sophomore ) = 25/(2 + 25 + 3)
Rewrite properly as:
So, we have:
Divide 25 by 30
Pr = 0.83
Hence, the probability of a student taking the bus given that the student is a sophomore is 0.83

Answer:
Step-by-step explanation:
Let w and l be the width and length of the garage.
Let and
be the area of garage at present and new garage.
Given:
The area of the garage at present
And he planed to tripling the dimensions of the garage.
We need to find the area of the new garage.
Solution:
We know the area of the rectangular garage.
---------------(1)
The dimension of the new garage is triple, so the area of the new garage is.
Substitute from equation 1.
Therefore, the area of the new garage
