Isabella built a time travel machine, but she can't control the destination of her trip. Each time she uses the machine she has a
0.25
0.250, point, 25 probability of traveling to a time before she was born. During the first year of testing, Isabella uses her machine
5
55 times.
Assuming that each trip is equally likely to travel before Isabella was born, what is the probability that at least one trip will travel before Isabella was born?
Round your answer to the nearest hundredth.
P
(
at least one before she’s born
)
=
P(at least one before she’s born)
