June will spin the arrow on the spinner 5 times. What is the probability that the arrow will stop on A, then B, then C, then D,
inessss [21]
Ok so assuming the board only has 4 spaces to land on (A,B,C,D) all we need to do is weight the probability, 

1/4 x 1/4 x 1/4 x 1/4 x 1/4 = 1/1024 

To solve I put the number of favorable outcomes over the number of total outcomes, in this case we had 1 favorable outcome each time and a constant of 4 possible outcomes.

Gina ate 3/4 of an apple pie. greg ate 1/8 of the same pie. how much of the Apple pie was left?
miskamm [114]
There would be 1/8 of the pie left,
you have to add 3/4 and 1/8 to find the total eaten and then subtract it by 8/8 (the total) which would give you your answer.

Hope it helps
