The probability is \( \frac{1}{4} \).

Solución

To find the probability that a randomly chosen month starts with the letter \( J \), we first need to identify the months that start with \( J \). The months of the year are: 1. January 2. February 3. March 4. April 5. May 6. June 7. July 8. August 9. September 10. October 11. November 12. December The months that start with the letter \( J \) are: - January - June - July So, there are 3 months that start with \( J \). Next, we calculate the total number of months, which is 12. The probability \( P \) that a randomly chosen month starts with the letter \( J \) is given by the formula: \[ P(J) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{3}{12} \] Now, we simplify \( \frac{3}{12} \): \[ P(J) = \frac{1}{4} \] Thus, the probability that the month starts with the letter \( J \) is \( \frac{1}{4} \). The correct answer is \( \frac{1}{4} \).

In a year, there are 12 months: January, February, March, April, May, June, July, August, September, October, November, and December. The months that start with the letter "J" are January and June, giving us a total of 2 months. Therefore, the probability of selecting a month that starts with "J" is \( \frac{2}{12} \) which simplifies to \( \frac{1}{6} \). The probability of selecting a month that starts with the letter "J" can be calculated easily with a simple ratio. Knowing that there are 2 months beginning with "J" out of a total of 12, you can simply divide the number of favorable outcomes (2) by the total number of outcomes (12). Just remember, probability is all about how likely something is to happen based on the options available!
