In conditional probability, the notation P(
AB) is read:
"The probability of event A occurring given that event B has
occurred."
For example: In the following two-way table
P(Walk to school Sophomore) = 37 (2 + 25 + 3) = 0.1

Answer :

Answer:

0.83

Step-by-step explanation:

It’s right use the formula they give you

MRROYALGO

The probability of a student taking the bus given that the student is sophomore is 0.83

Given that:

P(Walk to school | Sophomore) = 3 /(2 + 25 + 3) = 0.1

To cal culate the probability of a student taking the bus given that the student is sophomore, we make use of:

P(Take the bus | Sophomore ) = 25/(2 + 25 + 3)

Rewrite properly as:

[tex]Pr= \frac{25}{2 + 25 + 3}[/tex]

So, we have:

[tex]Pr= \frac{25}{30}[/tex]

Divide 25 by 30

[tex]Pr= 0.83[/tex]

Hence, the probability of a student taking the bus given that the student is sophomore is 0.83
