-14+?= -17
?= -17+14
?= -3
Answer:

Step-by-step explanation:
The probability of success (getting heads) on one roll DOESNT affect other rolls, so we need to find probability of getting a head in a roll.
Probability is defined as the number of favorable outcomes divided by the total number of outcomes.
<em>Here, favorable outcome is getting a head. So, on one roll, getting a head is 1. Also, the total number of outcomes is either a head or a tail. So total number of outcomes is 2.</em>
Thus,
P(Heads) = 1/2
84 I'm sure it's that I did it before
Multiply by -4 on both sides.
this makes z<-8
there is no drawing how should I do
