Given the statement:
A month of the year is chosen at random
Determine the probability that the month starts with the letter J or the letter M?
There are 12 months in a year
2 months starts with M, which is May and March
3 months starts with J, which is January, June and July
Therefore 5 months in a year either starts with J and M.
Solution:
We can write the probability as,
= 5/12
= 0.42 or 42%
Final answer:
The probability of picking a month that starts with either J and M is 42%.
