Answer:

  • P(Take the bus U Walk) =3/5

Step-by-step explanation:

According to table we can find that

Number of students taking the bus:

  • 25 + 20 + 5 = 50

Number of students walking to school:

  • 3 + 2 + 5 = 10

Number of students either take the bus or walk:

  • 50 + 10 = 60

Required probability is:

  • P(Take the bus U Walk) =
  • (number of students either take the bus or walk) / (total number of students) =
  • 60/100 =
  • 3/5
