3% percent of the students at Lincoln High School are in orchestra, 5%

are in band and 1% are in both. If a student is selected at random, what is

the probability that the student is in orchestra OR band?

The probability of a student to be in the orchestra or the band is 0.07 or 7%.

Step-by-step explanation:

The probability of a student to be in the orchestra or the band is given by the following formula:

p (orchestra or band) = p (orchestra) + p (band) - p (orchestra and band)

p (orchestra or band) = 0.03 + 0.05 - 0.01

p (orchestra or band) = 0.08 - 0.01

p (orchestra or band) = 0.07

The probability of a student to be in the orchestra or the band is 0.07 or 7%.
