Answer:
chances chances of happening = 0.0119
Step-by-step explanation:
given data
bet = $5
independent fair games = 50
solution
we will think game as the normal distribution
so here mean is will be
mean = [tex]\frac{50}{2}[/tex]
mean = 25
and standard deviation will be
standard deviation = [tex]\sqrt{50*0.5*0.5}[/tex]
standard deviation = 3.536
so
we have to lose 33 out of 50 time for lose more than $75
so as chance of doing things z score is
z score = [tex]\frac{33-25}{3.536}[/tex]
z score = 2.26
so from z table
chances chances of this happening = 0.0119
