Explanation

To find P(A ∪ B), we use the formula for the probability of the union of two events:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

Given:

• P(A) = 0.3
• P(B) = 0.4
• P(A ∩ B) = 0.1

Substituting the values: $P(A \cup B) = 0.3 + 0.4 - 0.1 = 0.6$

Therefore, the probability that the team wins at least one of the two events is 0.6.

Key Concepts:

• Union Probability: The probability that at least one of the events occurs
• Intersection Probability: The probability that both events occur simultaneously
• Inclusion-Exclusion Principle: Accounts for the overlap between events to avoid double-counting
