There are no solutions. By definition of absolute value, , so . The left side will always be positive, and a positive number cannot also be negative.
The probability of event B is P(B) = 0.9474 rounded to 4 decimal places
Step-by-step explanation:
Let us revise the meaning of independent probability
- Two events are independent if the result of the second event is not affected by the result of the first event
- If A and B are independent events, the probability of both events is the product of the probabilities of the both events
- P (A and B) = P(A) · P(B)
∵ A and B are independent events
∴ P (A and B) = P(A) · P(B)
∵ P(A) = 0.76
∵ P(A and B) = 0.72
- Substitute these values in the rule above
∴ 0.72 = 0.76 . P(B)
- Divide both sides by 0.76
∴ P(B) = 0.9474
The probability of event B is P(B) = 0.9474 rounded to 4 decimal places
