If a, b, and c are mutually exclusive events with p(a) = 0.2, p(b) = 0.3, and p(c) = 0.4, determine the following probabilities: a. p(a ∪ b ∪ c) b. p(a ∩ b ∩ c) c. p(a ∩ b) d. p[(a ∪ b) ∩ c] e. p(a′ ∩ b′ ∩ c′)

a. The events are mutually exclusive, so

b. For the same reason,

Another way to see this is to use the result from part (a), and the inclusion/exclusion principle:

and the right side reduces to 0.

c. Same as (b),

d. Same as (b),

We can also use the distributivity rule for unions and intersections to write

e. If the is the complement of , then by DeMorgan's law,

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
