Answer:
the volume would be 84
Step-by-step explanation:
multipacation
One fifth of the participants is 1/5*100=100/5=20 is the number of the participants given medicine. So the number of participants given placebo is 100-20=80.
80% of the 80 who took placebo felt improvements, so 20% of 80, which is
(20/100)*80=(2/10)*80=160/10=16 is the number of participants who took placebo and felt no improvement.
P(choosing participant who took placebo and felt no improvement)=
n(participant who took placebo and felt no improvement)/n(participants)
=16/100=0.16
X greater than or equal to 2
