Best Answer

If he is rolling a DIE he has 1/6th chance of getting a 5 1/6 x 270 = 45 out of 270 rolls

If he is rolling a PAIR of DICE he has a 4 out of 36 chanc eof rolling 5 4/36 x 270 = 30 out of 270 rolls

A dice has 6 sides so the probability of getting a 5 is 1/6, so divide 270 by 6. 270÷6=45. Jayden will roll a five 45 times.

I read it as one die too, Darkfox....but EP's second interpretation could also be correct....

Whatever.....good answers....!!!!!
