Answer:
y 3 4 5
___________________________________
P(Y) 0.1875 0.5 0.3125
Step-by-step explanation:
For this case we have the following statement : SOME DOGS ARE BROWN
And if we count the number of letters in the statement we have 16 possible letters. We can define the following random variable
Y= Length of word containing a selected letter.
For example the word DOGS have 4 of the total 16 letters, so we can define the probability using empirical approximation for each word like this:

And similar for the other words we have:



And we have the following distribution for the words in the statement with the random variable Y defined previously:
Word SOME DOGS ARE BROWN
________________________________________
y 4 4 3 5
P(Word) 0.25 0.25 0.1875 0.3125
And as we can see the possible values for Y are 3,4 and 5, so then we can define the probability distribution for Y like this:
y 3 4 5

P(Y) 0.1875 0.5 0.3125
Answer:
70th term is 753
Step-by-step explanation:
a70= ?
n= 70 (nth term, term to find)
a1= -6 (first term)
d= 11 (common difference)
a70= a1 + (n - 1)d
a70= -6 + 69(11)
a70= -6 + 759
a70= 753
Answer:
x=5
Step-by-step explanation:

cross multiply
45=9x
solve for x by dividing 9 to get x alone
5=x
Step-by-step explanation: 3
