Answer: (0.829, 0.903)

Step-by-step explanation:

We know that $a\pm b=(a-b,\ a+b)$ (1)

The given confidence interval : 0.866 ± 0.037

To express the given confidence interval in open interval form , we split the given expression as :

$0.866 \pm 0.037 \\\\=(0.866-0.037,\ 0.866+0.037)\ \ \text{[By using (1)]}\\\\=(0.829,\ 0.903)$

Therefore, the confidence interval in open interval form would be (0.829, 0.903) .

Inclusion-exclusion formula for 3 events. write aubuc = (aub)uc and use the inclusion-exclusion formula three times to derive th

nadya68 [22]

solution:

We are going to use this property: P(A U B) = P(A) + P(B) – P(AB)

First we treat (A U B) as one event as follows:

P( (A U B) U C) = P( A U B ) + P(C) – P((A U B)C)

= P( A U B ) + P(C) – P(AC U BC)

= P(A) + P(B) – P(AB) + P(C) – P(C) – P(AC U BC )

=P(A) + P(B) – P(AB) + P(C) –P(AC) – P(BC) + P(ABC)

= P(A) + P(B) + P(C) – P(AB) – P(AC) – (BC) + P(ABC)
