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%
Answer:
• 5 and 11
• 4 and 6
Step-by-step explanation:
"Alternate" means they are on opposite sides of the same line. "Exterior" means neither is between the lines being crossed.

Answer:
213.07 m
Step-by-step explanation:
We need to convert to the same units before subtracting.
The length of Ravi's rope is 214 meters.
If he gave 93 centimeters to his brother, then he didn't give up to a meter.
The reason is that, 100cm makes 1m.
Therefore 93cm makes 0.93m
We now set up the subtraction problem:
Therefore Ravi has 213.07m of rope left.
