Question

78.2% of the 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. (1 point) 0.218 0.782 0.328 0.391

Explanation:

Step1: Use the complement rule

The complement rule states that \(P(\text{not }A)=1 - P(A)\). Let \(A\) be the event that a student studies more than one day. We know \(P(A) = 0.782\).

Step2: Calculate the probability

$$P(\text{not }A)=1 - 0.782=0.218$$

Answer:

0.218
