Explanation Given: z 1 = − 1.83 z 2 = − 0.91 Explanation: Consider the table of area the under the normal curve and find the value of the area from the given standard deviation number. Find the value of the area for z 1 = − 1.83 from the table as follows: Take the intersection of row of − 1.8 and column of 0.03 . Thus, the value of the area for z 1 = − 1.83 is 0.0336 . Find the value of the area for z 2 = − 0.91 from the table as follows: Take the intersection of row of − 0.9 and column of 0.01

Find the general solution to the differential equation

3. A room has a large circular table with ten seats, numbered 1 to 10, such that to the right of seat number i is seat number i + 1 for all i ∈ {1, . . . , 9} and to the right of seat 10 is seat 1. We want to assign seats to 10 people, 6 of them only speak Slovene, 1 of them only speaks English, and the remaining 3 speak both Slovene and English, by giving out numbered place cards. In how many ways can we do that so that everyone sits next to at least one person who speaks a common language?
