This week in school, there is a 75 percent probability of having a fire drill, a 50 percent probability of a tornado drill, and a 25 percent probability of having both drills. Let event F be a fire drill and event T be a tornado drill. Are the two events independent? No, because P(F ∩ T) ≠ P(F) • P(T). No, because P(F ∩ T) ≠ P(F) + P(T). Yes, because P(F ∩ T) = P(F) • P(T). Yes, because P(F) = P(T) + P(F ∩ T).

A "No, because P(F ∩ T) ≠ P(F) • P(T)."

Step-by-step explanation:

option A.)  "No, because P(F ∩ T) ≠ P(F) • P(T)."

Step-by-step explanation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

answer: huh
