# The probability that a randomly selected K-12 teacher from a city is a female is 0.68. The probability that the teacher holds a second job.?

Question is: The probability that a randomly selected K-12 teacher from a city is a female is 0.68. The probability that the teacher holds a second job is 0.34. The probability the teacher is a female and holds a second job is 0.26. Find the probability that a K-12 teacher selected at random from this city is a female OR holds a second job.

I keep getting 1.02. Comes up as wrong.

Define two events.

F: The teacher is female.

J: The teacher holds a second job.

The given conditions:

P(F) = 0.68

P(J) = 0.34

P(F ∩ J) = 0.26

What you want is P(F U J).

P(F U J)

= P(F) + P(J) - P(F ∩ J)

= 0.68 + 0.34 - 0.26

= 0.76
