${\huge{\underbrace{\overbrace{\color{aqua}{Question:-}}}}}$

A pair of the die is thrown. Find the probability of getting a sum of 10 or more, if 5 appears on the first die.

$\huge \orange{ \underline \red{ \underline \purple{SOLUTION:-}}}$

Total number of outcomes = 36

Let A be the event of getting the sum of 10 or more.

Since, 5 appears on the first die.

So, elementary events favourable to the event A are (5, 5) and (5, 6)

Favourable number of outcomes = 2

So, PA = Favourable number of outcomestotal possible outcomes = 236 = 118.

Therefore the required probability is 1/18.
