Answer 1

We know that Number of days in January = 31(Leap year and non-leap year).

= > 4 weeks +  3 days.

Now,

For those 3-days, there are 7-possibilities, they are:

(a) Mon, Tues, Wed

(b) Tues, Wed, Thur

(c) Wed, Thurs, Fri

(d) Thurs, Fri, Sat

(e) Fri, Sat, Sun

(f) Sat, Sun, Mon

(f) Sun, Mon, Tue

The total number of possible outcomes = 7.

The number of outcomes having Mondays = 3.

Therefore Required Probability = 3/7.


Hope this helps!
