Question

WILL MARK BRAINLIEST FOR QUICK AND CORRECT ANSWER Determine the sum of the given probabilities. Are the events complementary? P(A) = 4/7 ; P(B) = 1/7 ; The events are complementary. ; The events are not complementary. ; The events are complementary. ; The events are not complementary.

Answer 1

Step-by-step explanation:

The numical sum of probabilities P(A) and P(B) = 4/7+1/7 = 5/7

Events A and B cannot be complementary because complementary events have their probabilities add up to exactly one.

Since P(A)+P(B)=5/7, A and B cannot be complementary.
