A red dye, a black dye, and a white dye.
00:11
And i want to know the probability of rolling an ace or a one.
00:18
The probability of no ace, two, three, four, five, or six for all three dye.
00:30
So that probability is five out of six to the power of three for each of those three dye.
00:36
We'll give us the probability of 125 over 216.
00:44
Of at least one ace, just the probability of no.
00:54
So 1 minus 125 over 216 that we just found above, i mean 91 over 216.
01:04
Above 1 .1 .1 .5 .0 .5.
01:11
Because it would be 1 .6, it would be 5, 6, because i don't want an ace.
01:19
I'll do that for each of my three dye, so i'll multiply by three.
01:26
Ability of 25 over 72.
01:39
I switch these two.
01:41
So an ace on red only, on that red only, on that run, so one six, times five, six, times five, six...
