@Michele_Laino please explain both parts
Mehek (mehek14):
for part A
experimental is based on the event
so write down the number of \(\dfrac{heads}{total}\)
Mehek (mehek14):
for B, there are 2 sides
so \(\dfrac{1}{2}\) chance for both
or 50%
OpenStudy (nuccioreggie):
Can you give me part A again Please @Mehek14
Mehek (mehek14):
you are told that isla got heads 9 times
the experimental is based on what happened
\(\dfrac{heads}{total}=\dfrac{9}{30}=\dfrac{3}{10}\)

Mehek (mehek14):
and why did you put 9/30 twice?
OpenStudy (nuccioreggie):
Ok i just changed it anythin else wrong?
Mehek (mehek14):
no
OpenStudy (nuccioreggie):
Because 9 is heads and 30 is the total
Mehek (mehek14):
9/30 = 3/10
