Answer:
0.40951
Step-by-step explanation:
P(none in five years) = 1 - 0.1 = 0.9
P(at least one) = 1 - P(none in five years)
= 1 - 
= 1 - 0.59049
= 0.40951
So the probability of a hurricane hit at least once in the next 5 years is 0.40951

Step-by-step explanation:
Answer:
0.200
Step-by-step explanation:
The probability of obtaining a 3, in one roll of a fair die is 1/6.
Now, we have 5 rolls.
We now want to know the probability of a 3 showing up in at least one of the rolls.
This simply mean, we add the probabilities of three showing one time plus probability of three showing in 2 of the rolls e.t.c
This means we can have 3 showing up to 5 times.
We add the probabilities as follows:
(1/6) + (1/6)^2 + (1/6)^3 + (1/6)^4 + (1/6)^5 = 0.199974 = 0.200
