Answer 2

Concept

Probability

Probability is a metric for determining the possibility of an event occurring. Many things are impossible to forecast with 100% accuracy. Using it, we can only anticipate the probability of an event occurring, i.e. how probable it is to occur. Probability can range from 0 to 1, with 0 indicating an improbable event and 1 indicating a certain event.

If is Probability of any event P(A)=$\frac{no. of possible outcomes}{No. of total outcomes}$.

Given

Three out of every five students in Middle School make the honor roll.

To find

The probability that a student does not make the honor roll (in %).

Solution

The probability that a student does honor roll is 3/5 = 60%.

The probability to do a task or not is 100%.

So not makeing the honor roll probability is 100% - 60%= 40%

Hence 40% probability student does not make the honor roll.
