A farmer from Whidbey Island: A man claims his whalebone can detect water. You design an experiment using a set of 4 cans, 3 empty, and one filled with water. You present the farmer with a total of 5 different but similar sets of cans. For each trial, you ask the farmer to identify which of the four cans has the water. How many cans would you expect the farmer to correctly identify by chance? (Round to the nearest 4 decimal places.)

The value is

Step-by-step explanation:

From the question we are told that

The number of cans is n = 4

The number of can that are empty is N = 3

The number of can filled with water is k = 1

The number number of sets of cans is w = 5

Generally probability of detecting the correct can is mathematically represented as

=>

=>

Generally probability of not detecting the correct can is mathematically represented as

Generally the number of cans expected of the farmer to correctly identify by chance is mathematically represented as

=>

=>

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
