Okay sy mash members Jaqen has to ten sided tice
- 00:06
He rolls both at the same time what's the probability
- 00:09
that both faces add up to a number less than
- 00:12
twenty There's only one way to roll us some greater
- 00:20
than or equal to twenty rolling two tens Any other

- 00:24
combination of faces adds up to a number less than
- 00:27
twenty much faster to find the probability of rolling two
- 00:29
tens and find the probability of all the other possible
- 00:32
roles so just take the shortcut there Well the probability
- 00:34
of rolling ten on one dies one in ten because
- 00:37
each of the ten faces has an equal probability of
- 00:40
turning up The probability of rolling to tens then is
- 00:43
one over ten times one over ten or one over
- 00:47
one hundred or one percent The probability of rolling anything
- 00:50
other than two tens and a rowing to faces that
- 00:53
add up to a number less than twenty is one
- 00:55
minus the probability of that one hundred shot So it's
- 00:59
ninety nine out of one hundred probability that both faces
- 01:02
add up to a number less than twenty is ninety
- 01:05
nine out of one hundred And yeah we like those
- 01:07
odds So the answer is c and we're so shmoop
