Sound is a form of energy, just like electricity and light. A sound is made when air molecules vibrate and move in a pattern called waves, or sound waves.
Answer: 1/15
Explanation:
Since it's a class of 6, and there are 2 students who forgot their lunch. The probability of firs choosing a student who forget their lunch will be 2 out of 6 which is 2/6.
When the next student who forget their lunch is picked there'll be 5 students left which means the probability then will be 1 out of 5 which is 1/5.
Therefore, the if the teacher chooses 2 students, the probability that both of them forgot their lunch will be 1/3 multiplied by 1/5 which will be:
= 1/3 × 1/5
= 1/15

The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less is 0.0020
<h3>What is probability? </h3>
Probability can be defined as the likelihood of an event to occur. In statistics, the mean of the sample distribution typically shows the probability of the population.
From the parameters given:
- The sample size (n) = 55 patients
- Let's assume that the mean (x) = 32 (i.e. 58.2%) of the patients
The sample proportion 
can be computed by using the expression:
If the percentage of the probability of all patients in the emergency room = 0.75
The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less can be computed as:
From the Z distribution table:
