The probability of events A and B is
P(A)=12
P(B)=13
P(A∩B)=14.
What is the value of P(A or B)?
Enter your answer as a fraction, like this: 4/25
pls help!!!!!!!!!!!!!!!!
To find the probability of A or B (denoted as P(A ∪ B)), we need to use the formula:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Given:
P(A) = 12
P(B) = 13
P(A ∩ B) = 14
Substituting the values into the formula:
P(A ∪ B) = 12 + 13 - 14
P(A ∪ B) = 25 - 14 = 11
Therefore, the value of P(A or B) is 11/25.
To find the probability of events A or B, we can use the formula:
P(A or B) = P(A) + P(B) - P(A∩B)
Given information:
P(A) = 12/100 = 3/25
P(B) = 13/100
P(A∩B) = 14/100
Using the formula:
P(A or B) = P(A) + P(B) - P(A∩B)
P(A or B) = 3/25 + 13/100 - 14/100
P(A or B) = 3/25 + (13-14)/100
P(A or B) = 3/25 - 1/100
P(A or B) = (3*4)/(25*4) - 1/100
P(A or B) = 12/100 - 1/100
P(A or B) = 11/100
Therefore, the value of P(A or B) is 11/100.
Probabilities are numbers between 0 and 1.
Your given probabilities make no sense
Once you have determined where your typos are, sub into
P(A or B) = P(A) + P(B) - P(A∩B)
