Answer: The required probability of event B is P(B) = 0.37.
Step-by-step explanation: For two events A and B, we are given the following probabilities :
P(A) = 0.34, P(A ∩ B) = 0.27 and P(A ∪ B) = 0.44.
We are to find the probability of event B, P(B) = ?
From the laws of probability, we have

Thus, the required probability of event B is P(B) = 0.37.
Answer:
One, two, six, four, twelve are some greatest common factors.
Step-by-step explanation:
Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
If the top of the fraction is less than the bottom, the fraction is less than one. However, Federico has raised 11/10 of what he needs and the top is bigger than the bottom so he’s raised the most money.
