Aguidance counselor reports that in a given semester, the probability that a student chooses art as an elective is 15 percent, the probability that a student chooses art or drama is 20 percent, and the probability that a student chooses both art and drama is 2 percent. what is the probability that a student chooses drama as an elective? 5 percent 7 percent 33 percent 37 percent it is not a.

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.
