Answer:

A) 0.15

P(A and B) = 0.68

Step-by-step explanation:

edge 2020

Pr ( A & B ) , ie Probability (Senior Student with Statistics) = 0.15

Given : Event A = Student is senior, Event B = Student takes statistics

  • Total Students = Seniors with Statistics + Juniors with Statistics + Seniors with Calculus + Juniors with Calculus = 15 + 18 + 35 + 32 = 100 students
  • Pr (A & B) , ie Probability (Senior Student with Statistics) = 15 students

Pr (A & B) = Favourable Students / Total Students = 15 / 100

P = 0.15
