The probability that a randomly selected student did not study more than one day for the test is equal to 1 minus the probability that a randomly selected student did study more than one day for the test.
We are given that 78.2% of students study more than one day for the test. Therefore, the probability that a randomly selected student did study more than one day for the test is 78.2% or 0.782.
The probability that a randomly selected student did not study more than one day for the test is 1 - 0.782 = 0.218.
So, the probability that a randomly selected student did not study more than one day for the test is 0.218 or 21.8%.
78.2% of students study more than one day for the chapter test. Find the probability that a randomly selected student did not study more than one day for the test.
