Aspinner numbered 1 through 8 is spun 3 times. what is the probability of spinning an even number, then an odd number, and then an 8? write your answer as a decimal. do not round

An even number would be 2 4 6 8 You can have any number between 1 and 8 so the probability of throwing an even number to start with is 4/8

An off number would be 1 3 5 7. That is also 4/8

An 8 can only be thrown 1 way so the answer here is 1/8

(4/8) * (4/8) * (1/8) = 16 / 512. Since you want a decimal you don't have to reduce this, but it does reduce.
16 ÷ 512 = 0.03125 probability of throwing an even an odd and an 8 in that order.
0.03125 <<< Answer

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
