The range of a lighthouse is the maximum distance at which its light is visible. In the figure, point A is the farthest point fr

om which it is possible to see the light at the top of the lighthouse L. The distance along Earth, s, is the range. Assuming that the radius of the Earth is 4000 miles, find the range of Marblehead Lighthouse to the nearest tenth of a mile. Enter only the number. (Hint: Notice the right triangle EAL with right angle A. Find the length EL, then subtract the radius of the Earth to find the height of the lighthouse.)

Michael wants to take French or Spanish, or both. But classes are closed, and he must apply and get accepted to be allowed to en
Brums [2.3K]

Answer:

80%.

Step-by-step explanation:

Given the following probabilities:

  • P(Micheal Being admitted to French), P(F)=50%
  • P(Micheal Being admitted to Spanish), P(S)=50%

In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:

  • P(Micheal Being admitted to BOTH French and Spanish), P(F \cap S)=20\%

We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).

Probability of either A OR B =P(F \cup S)

From Probability Theory:

P(F \cup S) = P(F)+P(S)-P(F \cap S)\\P(F \cup S) =50+50-20\\P(F \cup S) =80

The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.
