Answer 1

ooooh Mthswath again. a=8 b=1/8 c=4/8 or 1/2

Explanation:

a= there are 8 outcomes you can multiply the outcomes. 2×2×2=8

b= (i don't want to insert a picture again, as I already did for the last one you asked) So it is 1/8

c= Again, list out all the possibilities and you will find there are 4 with at least 2 tails or simplify it, 1/2
