Question

A pair of fair dice are thrown.Find the probability that the sum is 10 or greater if a 5 appears in the first die

Answer 1

So this way the answer is 1/3

Answer 2

$If \: a \:pair \: of \:fair \:dice \:are \:thrown \\then \\\blue{number \:of \: total\: possible \: outcomes = 36}$

$Favourable \: outcomes = \{(5,5), (5,6) \}$

$\orange { Number \:of \: favourable \: outcomes = 2}$

$Probability = \frac{(2)}{(1)} \\= \frac{2}{36} \\= \frac{1}{18}$

Therefore.,

$\red{Required \: Probability }\green {= </p><p>\frac{1}{18}}$
