OpenStudy (dan815):

1/infinity

Idk please help lol @jim_thompson5910

jimthompson5910 (jim_thompson5910):

how many tiles have "1" on it? how many tiles are there total?

OpenStudy (winsteria):

only 1 and there are 4

jimthompson5910 (jim_thompson5910):

so the probability of drawing a "1" is 1/4 = 0.25

jimthompson5910 (jim_thompson5910):

the probability of drawing "1" three times (with replacement) in a row is (1/4)^3 = ???

OpenStudy (winsteria):

0.015625

jimthompson5910 (jim_thompson5910):

yes that's the probability in decimal form

jimthompson5910 (jim_thompson5910):

how about in fraction form?

OpenStudy (winsteria):

Idk
