The sample space for flipping a coin three times is given. let h represent heads and t represent tails

(h, h,h) (h, t,t)
(h, h,t) (t, h,t)
(h, t,h) (t, t,h)
(t, h,h) (t, t,t)

find the probabilities of the following events using the above sample space
a. 2 heads, 1 tail
b. 3 heads
c. 2 tails, 1 head
d. 3 tails
e. the sum of the probabilities equals

, are a and c the same 3/8?
and b and d as well 1/8?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
