Two days later, the National Hurricane Center projected the path of Isaac would pass directly over Cuba before reaching the Gulf of Mexico. Hurricanes that reach the Gulf of Mexico have a .08 probability of having passed over Cuba. Tropical storms that reach the Gulf of Mexico have a .20 probability of having passed over Cuba. How did passing over Cuba alter the probability that Isaac would become a hurricane by the time it reached the Gulf of Mexico? Use the above probabilities to answer this question.

Here is the missing part of the question.

In August 2012, tropical storm Isaac formed in the Caribbean and was headed for the Gulf of Mexico. There was an initial probability of .69 that Isaac would become a hurricane by the time it reached the Gulf of Mexico (National Hurricane Center website, August 21, 2012).

Two days later, the National Hurricane Center projected the path of Isaac would pass directly over Cuba before reaching the Gulf of Mexico. Hurricanes that reach the Gulf of Mexico have a .08 probability of having passed over Cuba. Tropical storms that reach the Gulf of Mexico have a .20 probability of having passed over Cuba. How did passing over Cuba alter the probability that Isaac would become a hurricane by the time it reached the Gulf of Mexico? Use the above probabilities to answer this question.

Thus, passing over Cuba alter the probability that Isaac would become a hurricane by the time it reached the Gulf of Mexico in the sense that passing over cuba tends to slow down Tropical storms. This  further implies that the probability that Isaac would become a hurricane by the time it reached the Gulf of Mexico depreciates from 0.69 to 0.4701.

Step-by-step explanation:

From the given information;

Let  q represent the event that Isaac passes over cuba

Let R represent the event that Isaac become a hurricane by the time he reaches the Gulf of Mexico

Let S represent the event that Isaac does not become a hurricane and remains a Tropical storm when it reaches the Gulf of Mexico

P(R) = 0.69

PS) = 1 - P(R)

P(S) = 1 - 0.69

P(S) = 0.31

We know that ;

P (q/R) = 0.08

P(q/S) = 0.20

Then:

Therefore,  passing over Cuba alter the probability that Isaac would become a hurricane by the time it reached the Gulf of Mexico in the sense that passing over cuba tends to slow down Tropical storms. This  further implies that the probability that Isaac would become a hurricane by the time it reached the Gulf of Mexico depreciates from 0.69 to 0.4701.

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
