Which of the following are compound events in which the results of one event affect the likelihood of the other event?

dependent events
fair events
independent events
theoretical events

Dependent Events

Step-by-step explanation:

The answer is dependent events because a dependent event relies on the outcome of another event.  Remember dependent depends on another event.

answer: 7 percent.

step-by-step explanation:

since here, probability of choosing arts,   p(a)= 15%

probability of choosing arts and drama = 2%

probability of choosing arts or drama = 20%

probability of choosing dramas, p(d)=?

since, we know that,

⇒20 = 15+ p(d) - 2

⇒ p(d) = 20-15+2= 7

⇒ p(d) = 7%

therefore, 7 % is the   probability that a student chooses drama as an elective.
