I know for sure it is 1/2 Would I multiply 1/2 4 times?
How many sides are on a coin?
2.
That means she has a 50% chance every time she flips a head
If she flips a coin 4 times she still has a 50-50 chance of getting a head

So it would be 1/2*1/2*1/2*1/2 =1/16? Is that right
at least one head means one head and one write + two head no write 1/2*1/2 +1/2*1/2=2/4=1/2
you could also find the probability of "no heads" and subtract it from 1
yeah hehehe
\[1-\left(\frac{1}{2}\right)^4=\frac{15}{16} \]
