If a die is rolled 40 times, there are 640 different sequences possible. the following question asks how many of these sequences satisfy certain conditions. hint [use the decision algorithm discussed in example 3 of section 6.3.] what fraction of these sequences have exactly five 1s? (round your answer to four decimal places.)

0.1433

Step-by-step explanation:

The total number of different sequences in 40 rolls of a die is

                         The 1s may occur at any 5 rolls among 40. The number of ways of exactly five 1s occuring is therefore, equivalent to number of ways of selecting 5 fruits from 40 distinct fruits which is ⁴⁰C₅ ways. These 5 rolls have a fixed outcome 1. Other 35 rolls each have 5 possible outcomes : 2 or 3 or 4 or 5 or 6. So, the number of possible sequences of outcomes on other 35 rolls of the die is .

⇒The total number of different sequences having exactly five 1s in 40 rolls of a die is (⁴⁰C₅)×()

∴The fraction of the total number of sequences having exactly five 1s is )}{}" alt="5^{35}" />)}{}" /> ≈ 0.1433

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
