Answer: b. 3
Therefore, we will have the same number of Mondays and Wednesdays if the first day is either Monday, Thursday or Friday. Making 3 possible days
Step-by-step explanation:
Given that there are 31 days in the month.
And there are equal number of Mondays and Wednesdays within a 7 day bracket.
30 - 4(7) = 3days
After four weeks we are left with three days.
So, if the first day is;
Monday - we will have 5 Mondays and Wednesdays each
Tuesday - we have more Wednesday
Wednesday - we will have more Wednesday
Thursday - we will have 4 Mondays and Wednesdays each
Friday - we will have 4 Mondays and Wednesdays each
Saturday - we will have more Monday
Sunday - we will have more Monday
Therefore, we will have the same number of Mondays and Wednesdays if the first day is either Monday, Thursday or Friday. Making 3 possible days
