Find the probability that a student at greendale Middle School takes both art and springs

Without information about the total number of students, it is impossible to calculate the exact probability that a student at Greendale Middle School takes both art and springs. However, if we have data on the number of students who take art and the number of students who take springs, we can use the formula for the probability of the intersection of two events:

P(A and B) = P(A) x P(B|A)

where P(A) is the probability of event A occurring, P(B|A) is the probability of event B occurring given that A has occurred.

For example, if we know that 50% of Greendale Middle School students take art and 30% take springs, and that 20% of art students also take springs, we can calculate:

P(art and springs) = P(art) x P(springs|art)

P(art) = 0.5 (given)

P(springs|art) = 0.2 (given)

P(art and springs) = 0.5 x 0.2 = 0.1

Therefore, the probability that a student at Greendale Middle School takes both art and springs is 0.1 or 10%.
