Question

What word may be used instead of the symbol 'U' in the expression P(A ∪ B)?

a) And
b) Or
c) Not
d) If

Answer 1

The symbol 'U' in the expression P(A ⋃ B) is replaced by the word 'or,' indicating the probability of either event A, event B, or both occurring.

Step-by-step explanation:

The expression P(A ⋃ B) refers to the probability that either event A occurs, or event B occurs, or both. The correct word used instead of the symbol '⋃' (union) is 'or.' Therefore, the answer to what word may be used instead of the symbol 'U' in the expression P(A ⋃ B) is b) Or.

In probability theory, the union of two events represents the set of outcomes that belong to either one of the events or to both. For example, if Event A is rolling a die and getting an even number, and Event B is rolling a die and getting a number less than four, then P(A ⋃ B) is the probability of rolling an even number or a number less than four (or both).

Answer 2

The word that can be used instead of the symbol 'U' in the expression P(A ∪ B) is 'Or'.

The answer is option ⇒b

Step-by-step explanation:

When we use the symbol 'U' in a probability expression, it represents the union of two events, which means finding the probability that either event A or event B (or both) occur. The word 'Or' conveys the same meaning, indicating that we are looking for the probability of one or both events happening.The word that can be used instead of the symbol 'U' in the expression P(A ∪ B) is Or.

The answer is option ⇒b
