Answer 1

Answer 2

Total probability that both of your parents were born on a weekend is 4/49

What is probability?

• Probability refers to the chance of occurring of an event is called its probability.
• Probability is always ≤ 1

What are equally likely events ?

When the events have equal chance of occurring then the events are called equally likely events.

How to calculate the probability that both  parents were born on a weekend ?

• Probability can be found by dividing the favourable cases by the total possible cases.

Firstly, calculating probability that mother was born on a weekend.

• There are 7 days in a week, out of which there are 2 days in a  weekend.

∴ Total possible cases = 7

  Total favourable cases = 2

∴ Reqiured probability = 2/7

Similarly, probability that father was born on a weekend = 2/7

∴ Total probability that both of your parents were born on a weekend =

                                             (2/7) x ( 2/7) = 4/49

Total probability that both of your parents were born on a weekend is 4/49
