The following table represents the data collected from 200 conference attendees of different nationalities:
If a participant is selected, find his probability of speaking both Arabic and English.
In this case, event is selecting an Arabic speaker, and event
is selecting an English speaker. Since the sum of the number
of Arabic speakers, the number of English speakers, and the number
of French speakers equals the total number of conference
attendees, and must be mutually exclusive events. This
means that they cannot occur together. The probability of both
event and event occurring is equal to the number of
outcomes favorable for both events divided by the total number of
possible outcomes in the sample space, Find the probability
of both event and event occurring as follows:
Thus, the probability of selecting a participant who speaks both
Arabic and English is 0.
