The Florida Tourist Commission selected a random sample of 200 people that attended one or more concerts during the first weeken
Alina [70]

Answer:

0.8 or 80%

Step-by-step explanation:

Let A and B be the events

<em>A: “The concert goer went to Orlampa Skydome” </em>

<em>B: “The concert goer went to the Bithlo Megaplax” </em>

<em> </em>Then the probability P(A) that a concert goer went to Orlampa Skydome is

<em>P(A) = 120/200 = 0.6 </em>

Similarly,

<em> P(B) = 100/200 = 0.5 </em>

<em> </em>We are looking for P(A∪B), the probability that a concert goer went to Orlampa Skydome OR the Bithlo Megaplax.

We know that

P(A∪B) = P(A) + P(B) - P(A∩B)

but P(A∩B) is the likelihood that a concert goer went to Orlampa Skydome AND the Bithlo Megaplax.

Since the events are independent,  

<em> P(A∩B) = P(A)P(B) = 0.6*0.5 = 0.3 </em>

and

P(A∪B) = 0.6 +0.5 - 0.3 = 0.8 or 80%
