A survey of 100 high school students provided this frequency table on how students get to school: What is the probability that a randomly selected student is a senior or a student who drives to school ?

3/4

Step-by-step explanation:

Here, we want to calculate the probability that a student selected is a senior student or one that drives to school.

From the table, the number of senior students is 25 + 5 + 5 = 35

So the probability of selecting a senior student is 35/100 = 7/20

Now the probability of selecting a student that drives to school.

The number of students that drive to school is 2 + 13 + 25 = 40

So the probability of a student who drives to school is 40/100

Kindly recall that when we have or and we are dealing with probability, we add the concerned terms together

Thus the probability of randomly selecting a student who is a senior or drives to school = Probability of being a senior + Probability of driving to school = 35/100 + 40/100 = 75/100 = 3/4

Step-by-step explanation:

P ( senior or drives to school ) = number of seniors or drives to school / total

35 seniors + 40 drivers - 25 seniors who drive = 50

P( senior or drives to school) = number of seniors or drives to school / total

= 50/100

= 1/2                                              

california, bc u would have lots of freedom there.
