Practice makes perfect

We are given the length of shoreline along the Gulf of Mexico for each state that borders the body of water.

Texas Louisiana Mississippi Alabama Florida
367 mi 397 mi 44 mi 53 mi 770 mi
We will find the theoretical probabilities for each option that a ship coming ashore at a random point in the Gulf of Mexico lands in the state. To find the probability we need to find the total length of shoreline, so we will sum the given lengths. 367+ 397+ 44+ 53+ 770=1631miles From here we can find the probability of a ship landing in Texas by dividing the length of the shoreline of Texas by the total length of shoreline along the Gulf of Mexico.
P(Texas)=367/1631
P(Texas)=0.22506...
P(Texas)≈ 0.225
This time, we can find the probability of a ship landing in Alabama by dividing the length of the shoreline of Texas by the total length of shoreline along the Gulf of Mexico.
P(Alabama)=53/1631
P(Alabama)=0.032495...
P(Alabama)≈ 0.032
Next, we will find the probability of a ship landing in Florida.
P(Florida)=770/1631
P(Florida)=0.472103...
P(Florida)≈ 0.472
Finally, we will find the probability of a ship landing in Lousiana!
P(Lousiana)=397/1631
P(Lousiana)=0.243408...
P(Lousiana)≈ 0.243
