If AA and BB are two disjoint events with P(A)=0.15P(A)=0.15 and P(B)=0.75P(B)=0.75, find the following probabilities:

zubka84 [21]

Answer:

a 0

b) 0.9

c) 0.85

d) 0.25

e) 0.1

f) 0.0375

Step-by-step explanation:

As A and B are two disjoints events, then P(A and B) is

P(A and B)=0

As A and B are two disjoints events, then P(A or B) is

P(A or B)=P(A)+P(B)

P(A or B)=0.15+0.75=0.9

P(not A)=1-P(A)

P(not A)=1-0.15=0.85

P(not B)=1-P(B)

P(not B)=1-0.75=0.25

P(not (A or B))=1-P(A or B)

P(not (A or B))=1-0.9=0.1

P(A and (not B))=P(A)*P(not B)

P(A and (not B))=0.15*0.25=0.0375

The average of 11 numbers in a list is 14. If the average of 9 of the numbers in the list is 9, than what is the average of the

liberstina [14]

Total value of 11 numbers
14*11
154

Total value of 9 numbers
9*9
81

Total value of other 2 numbers
154 - 81
73

So average of other 2 numbers
73 / 2
36.5

Please help fast! 25 points and brainliest!!

Firlakuza [10]

Answer:

The answer is

Step-by-step explanation:

f(x) = 36x^5 − 44x⁴ − 28x³

g(x) = 4x²

To find f(x) / g(x) Divide each term of f(x) by g(x)

That's

$\frac{f(x)}{g(x)} = \frac{ {36x}^{5} - {44x}^{4} - {28x}^{3} }{ {4x}^{2} } \\ \\ = \frac{ {36x}^{5} }{ {4x}^{2} } - \frac{ {44x}^{4} }{ {4x}^{2} } - \frac{ {28x}^{3} }{ {4x}^{2} } \\ \\ = {9x}^{3} - {11x}^{2} - 7x$

Hope this helps you
