I need help with this fast. Please help! Find the complementary event of the given event. a number less than 5 on a roll of a number cube with faces labeled 1– 6
p=2/3
A. rolling a 5 B. rolling a 5 or 6 C. rolling a 4 or 5 D. rolling a 4 Those are my choices
b
Thanks @epoweritheta
Can you help me answer one more?
ya
Determine the sum of the given probabilities. Are the events complementary? P(red) = 2/5 ; P(blue) = 3/5
give the full Q , otherwise we may not know that the events are disjoint
that's the Question but the answers are, A. 1/2 the events are complimentary. B. 1/2 the events are not complimentary. C. 1 events are complimentary. D. 1 events are not complimentary.
okay may be the assumption is that the events ar disjoint , then u can add them as normal arithmetic , and if their sum=1 they are complementary
sorry I don't understand?
oh never mind I got it. thanks for the help!
