Answer:
a) 12/91
b) about 67 times; (66 2/3)
Step-by-step explanation:
a) total of frequencies is 90 and frequency for a 3 is 11
however, the question said if the dice is rolled once more, then that raises the 11 to 12 and the frequency total from 90 to 91
let 'x' = # of sixes rolled out of 500 times
b) 12/90 = x/500
cross-multiply:
90x = 6000
x = 66 2/3
