Answer:
D=2r
Step-by-step explanation:
all u do is get the diameter os for d so lets say d is 3 it will be like 3=2r now u need is the radis u need to divide the diameter by 2 and thwre u go
P(z ≤ -a) + P(-a ≤ z ≤ a) + P(z ≥ a) = 1 - P(z ≤ a) + [P(z ≤ a) - P(z ≤ -a)] + 1 - P(z ≤ a) = 2 - 2P(z ≤ a) + P(z ≤ a) - [1 - P(z ≤ a)] = 2 - P(z ≤ a) - 1 + P(z ≤ a) = 1
Therefore, option D is the correct answer.
