tudents attending an international event were asked if they can speak Arabic or Chinese. 25% speak Arabic, 20% speak Chinese, 10% speak both languages. Assume random selection: a. What is the probability that the student can speak Chinese or Arabic

P(A ∪ C) = 0.35

Step-by-step explanation:

Given:

25% speak Arabic

20% speak Chinese

10% speak both languages

Find:

Probability that the student can speak Chinese or Arabic P(A U C)

Computation:

P(A ∪ C) = P(A) + P(C) - P(A ∩ C)

P(A ∪ C) = 0.25 + 0.2 - 0.1

P(A ∪ C) = 0.35
