Answer :
The probability that the month choosen at random has 31 days or starts with the letter J is 5/6.
What is the probability?
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that the month choosen at random has 31 days or starts with the letter J = probability that a month starts with J + probability that the month has 31 days
Probability that a month starts with J = number of months that starts with J / months in a year
3/12
Probability that the month has 31 days = number of months with 31 days / months in a year
= 7/12
3/12 + 7/12 = 10 / 12 = 5/6
