Answer:
0.65 = 65%
Step-by-step explanation:
56% of the moviegoers were female: P(F) = 0.56
26% were under age 25: P(25-) = 0.26
17% were females under the age of 25: P(F ∩ 25-) = 0.17
Probability that a moviegoer is either female or under age 25: P(F ∪ 25-) = ?
We know that P (A ∪ B) = P(A) + P(B) - P(A ∩ B), so:
P(F ∪ 25-) = P(F) + P(25-) - P(F ∩ 25-) = 0.56 + 0.26 - 0.17 = 0.65

Answer:
x = 0.8
Step-by-step explanation:
2/3 = 1.2/x
First, flip the equation (personal preference)
1.2/x = 2/3
Multiply by 1.2 to isolate the variable.
x = 1.2 * 2/3
x = 0.8
