QUESTION: 4

A coin is tossed twice. The probability of getting both heads is

Solution:

Sample space - {HH, HT, TH, TT}
Number of total possible outcomes = 4

QUESTION: 6

The probability that a non leap year selected at random will contain 53 Sunday's is

Solution:

A non-leap year has 365 days

A year has 52 weeks. Hence there will be 52 Sundays for sure.

52 weeks = 52 x 7 = 364 days .

365– 364 = 1 day extra.

In a non-leap year there will be 52 Sundays and 1day will be left.

Of these total 7 outcomes, the favourable outcomes are 1.

Hence the probability of getting 53 sundays = 1/7.
