Ответ:
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,![p(a\cup d)=p(a) + p(d)-p(a\cap d)](/tex.php?f=p(a\cup d)=p(a) + p(d)-p(a\cap d))
⇒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.
