Events A and B are overlapping. P(A) = 4/11; P(B) = 3/11, P(A and B) =2/11 .

Find P(A or B).

5/11

Step-by-step explanation:

Since the events are overlapping...

P(A or B) = P(A) + P(B) - P(A and B)

P(A) = 4/11

P(B) = 3/11

P(A and B) = 2/11

P(A or B)  = 4/11 + 3/11 - 2/11

P(A or B)  = 5/11

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
