Answer:The answer is and the number in green box =7
Step-by-step explanation:
P(Sophomore| Girl)=?
We have P(A | B) =P(A∩B)/ P(B)
P(Sophomore∩Girls)=
Total Students =8+12+5+5 =30
Total girls =4+7+3+4 =18
P(Girls)=
P(Sophomore | Girl)=P(Sophomore | Girls)/P(Girls)
=
=
The number in green box =7
The attached diagram represents the tree diagram for three consecutive mornings.
<h3>How to draw the tree diagram?</h3>The probability of arriving on time is given as:
P(On Time) = 65%
Assume that the bus would definitely show up.
Then it means that the event is a binomial event and the possible outcomes are:
On Time and Late
The above means that the number of possible outcomes is 2.
For three consecutive mornings, the total outcome is:
Total = 2³
Evaluate
Total = 8
This means that the tree diagram would have 8 outcomes
Next, we draw the tree diagram (see attachment)
