Introduction
Probability is a fundamental concept in mathematics that deals with the likelihood of an event occurring. In this article, we will explore the probability of choosing a month of the year that starts with the letter J or M. We will analyze the possible outcomes, calculate the probability, and compare it with the given options.
Understanding the Problem
There are 12 months in a year, and we are interested in finding the probability that a randomly chosen month starts with the letter J or M. To solve this problem, we need to identify the months that meet this condition and calculate the probability accordingly.
Identifying the Months
The months that start with the letter J are January and June, while the months that start with the letter M are March, May, and June. However, since June is counted twice, we need to subtract it once to avoid double counting.
Calculating the Probability
There are 12 months in a year, and 5 of them start with the letter J or M (January, June, March, May, and June). However, since June is counted twice, we need to subtract it once to avoid double counting. Therefore, the total number of favorable outcomes is 5 - 1 = 4.
The probability of choosing a month that starts with the letter J or M is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Probability = Number of favorable outcomes / Total number of possible outcomes = 4 / 12 = 1/3
However, this is not among the given options. We need to simplify the fraction to match one of the options.
Simplifying the Fraction
To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 4 and 12 is 4.
Probability = (4 รท 4) / (12 รท 4) = 1 / 3
However, this is still not among the given options. We need to find another way to simplify the fraction.
Alternative Simplification
Another way to simplify the fraction is to divide both the numerator and the denominator by their common factor. In this case, both 4 and 12 have a common factor of 4.
Probability = (4 รท 4) / (12 รท 4) = 1 / 3
However, this is still not among the given options. We need to find another way to simplify the fraction.
Another Alternative Simplification
We can also simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 4 and 12 is 4.
Probability = (4 รท 4) / (12 รท 4) = 1 / 3
