Explain to me the answer?

- PROBABILITY MATH -
**Reiny**, Wednesday, November 9, 2011 at 8:03amThe prob of answering a question right (R) is 1/5, and the prob of answering it wrong (W) is 4/5

So you want the specific order of

RRRRW which would be (1/5)^4 (4/5) = 4/3125

**HM**, Wednesday, November 9, 2011 at 1:21pmI dont think it requires for it to be times by (4/5)

it is just asking for possibility of it being correct 4 times the first times..

so the answer is 1/625

:)

thank you reiny
