OpenStudy (amistre64):

P(2)*P(2)*P(2) id assume

OpenStudy (anonymous):

what?

OpenStudy (amistre64):

the probability of rolling a 2 * itself ... 3 times

OpenStudy (amistre64):

how many 2s are on a 6sided dice?

OpenStudy (anonymous):

4?

OpenStudy (amistre64):

i dont think there are four 2s on a six-sided dice ....

OpenStudy (anonymous):

1

OpenStudy (amistre64):

1 is good; so the chance of success is 1 the total sample space is 6 prob = chance of success, divided by total sample space: 1/6

OpenStudy (anonymous):

thanks so much!

OpenStudy (amistre64):

1/6 * 1/6 * 1/6 should be the prob of rolling a 2, three times in a row

OpenStudy (anonymous):

so its 1/6 right?

OpenStudy (anonymous):

or 1/216

OpenStudy (amistre64):

1/6 is only the probability of rolling a 2; i would go with the 1/216 for a complete result
