During the month of April 2006, at least some rainfall was recorded on 12 different days at the Sarnia Airport weather station. Suppose one day in April 2006 is selected at random. What is the probability of choosing a day on which it rained as a percent?
12/30 = 2/5 = ___ %
To find the probability, we need to know the number of days on which it rained and the total number of days in April 2006.
Given that some rainfall was recorded on 12 different days at the Sarnia Airport weather station in April 2006, we know that the number of days it rained is 12.
The total number of days in April is usually 30, but to avoid any assumptions, we will assume the total number of days is 30 and not provided in the question.
Therefore, the probability of choosing a day on which it rained can be calculated as:
Probability = Number of days it rained / Total number of days
Probability = 12 / 30
Now, we can calculate the probability as a percentage:
Probability = 12 / 30 * 100
Probability ≈ 40%
Therefore, the probability of choosing a day on which it rained in April 2006 at the Sarnia Airport weather station is approximately 40%.
To find the probability of choosing a day on which it rained in April 2006, we need to know the total number of days in April 2006 and the number of days on which it rained.
First, we need to determine the total number of days in April 2006. April has 30 days.
Next, we need to know the number of days on which it rained. According to the information provided, rainfall was recorded on 12 different days.
To calculate the probability, we divide the number of days on which it rained by the total number of days in April 2006 and multiply by 100 to express it as a percentage.
Probability (as a percentage) = (Number of days on which it rained / Total number of days in April 2006) * 100
Probability = (12 / 30) * 100
Probability = 0.4 * 100
Probability = 40%
Therefore, the probability of choosing a day on which it rained in April 2006 is 40%.
