What are the probabilities that a sea turtle lays its eggs in front of John’s house, depending on which street he lives on?

A. \(\frac{4}{25}\)

B. \(\frac{1}{5}\)

C. \(\frac{4}{15}\)

D. \(\frac{1}{3}\)

Explanation

If you pare down the problem, then it is much simpler than it first appears. There will be 1 house on Surf Street at which a turtle will lay its eggs; this is “the number of outcomes you want.”

There are a total of 5 houses, which is the “total number of possible outcomes.” Therefore, if John spends the summer on Surf Street, the probability of John staying in the house where the sea turtle will lay its eggs is choice B, \(\frac{1}{5}\), and the information about the landside houses versus seaside houses actually turns out to be unnecessary.

Similarly, if John stays on Breaker Way, there will be 1 house that a turtle will lay its eggs at out of a total of 3 possible houses that John could live in. Therefore, if he lives on Breaker Way, there is a \(\frac{1}{3}\)chance that the turtle lays its eggs outsides John’s house, and this makes choice D correct.

But sandy the turtle can lay eggs in front of beach houses only then how we can include landslide houses??

As per my understanding answer should be only 1/5 as there are 5 beach houses in total

There are 5 houses on Surf street ( 1L,4B) and 3 houses on Breakway Street (2L,1B). Now John can live in any one of the houses.

If he lives in Surf street , possible outcomes - 5 (1L,4B) .Therefore Probablity(Surfstreet) = 1/5

Similary, If he lives in Breakway street , possible outcomes - 3(2L,1B) , Probablity(Surfstreet) = 1/5

Hence 1/5 , 1/3 are possible probabilities depending upon where John lives.

Correct Option B and D
