What is the probability of getting the number 6 at least once in a regular die if, I can roll it 6 times?

Question

jhonyy9 · Answer

in case of one roll there is 1/6 chance to get the number of 6 

yes ?

lynfran · Answer

agree

jhonyy9 · Answer

ok. so in case that can rolling 6 times so this mean that will get the chance 6*(1/6) = 6/6 = 1

@LynFran 
Hint:
I suggest you calculate the probability of NOT getting a 6 for six throws in a row.
Subtract this probability from one to get the probability of getting a six at lease once.

i end up with 0.665

p(y=0) ; 6C0*(1/6)^0 * (5/6)^6=0.33489
1-0.33489=0.665

doesn't seem likely

satellite73 · Answer

at least once mean not never

satellite73 · Answer

never would be $$\left(\frac{5}{6}\right)^6$$

satellite73 · Answer

oh whoops, you are right, sorry

satellite73 · Answer

$$1-(\frac{5}{6})^6=.665$$
