Since 1851, exactly 119 hurricanes have hit florida (this includes the years 1851 and direct hits by hurricanes are counted, not tropical storms). in 2005, florida was hit by four hurricanes: cindy, dennis, katrina, and wilma. if the probability of hurricane strikes has remained the same since 1851, what is the probability of florida being struck by four or more hurricanes in the same year?

There is a 0.58% probability of Florida being struck by four or more hurricanes in the same year.

Step-by-step explanation:

Since we have only the mean during the interval, we can solve this problem using the Poisson probability distribution.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

Poisson probability distribution

In which

x is the number of sucesses

is the Euler number

is the mean in the given time interval.

In this problem, we have that:

Since 1851, exactly 119 hurricanes have hit Florida (this includes the years 1851 and 2019). Counting 1851 and 2019, there are 169 years in this interval. This means that

If the probability of hurricane strikes has remained the same since 1851, what is the probability of Florida being struck by four or more hurricanes in the same year?

This is .

Either Florida is struck by less than four hurricanes in a given year, or it is struck by 4 or more. The sum of these probabilities is decimal 1.

In which

So

Finally

There is a 0.58% probability of Florida being struck by four or more hurricanes in the same year.

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
