Based on outcomes since 1967, the probability a team from the national league wins the baseball world series in any given year is 0.44. based on outcomes since 1967, the probability a team from the national football conference wins the superbowl in any given year is 0.53. assume whether a team from the national league wins the world series in a year is independent of whether a team from the national football conference wins the superbowl in the same year. what is the probability a team from the national league wins the world series in a given year or a team from the national football conference wins the superbowl in the same year?

0.7368

Step-by-step explanation:

Let the occurrence that a team from the National League wins the Baseball World Series be termed EVENT A

and the occurrence that a team from the National Football Conference wins the Superbowl be termed EVENT B

We assumed that Event A and Event B are independent.

This means that the probability of Event A occurring is the same, whether or not Event B occurs, and vice versa.

P(Event A) = 0.44

P(Event B)= 0.53

P(Event A or Event B) = P(A) + P(B) - P(A and B)

The keywords here are "or" and "and".

To get P(A or B), let's find P(A and B)

P(A and B) = 0.44 × 0.53 = 0.2332

P(A or B) = 0.44 + 0.53 - 0.2332 = 0.97 - 0.2332 = 0.7368

5x+10 is the correct one

hope this

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
