Complete question:
Calculate each probability given that P(A) = 0.2, P(B) = 0.8, and A & B are independent.
a) compute P(A and B)
b) If P(A|B) = 0.7, compute P(A and B).
Answer:
(a) P(A and B) = 0.16
(b) P(A and B) = 0.56
Step-by-step explanation:
Two events are independent if occurrence of one event does not affect possibility of occurrence of another.
(a) if A and B are independent, then P(A and B) = P(A) x P(B)
= 0.2 x 0.8
= 0.16
(b) If P(A|B) = 0.7, compute P(A and B)
Considering the notations of independent events,
= 0.7 x 0.8
= 0.56

Step-by-step explanation:
Given - Mean length of fish = μ= 73 cm
SD σ =8 c m
Number of fish having a length greater than 57 cm out of 480.
Find the value of z at x = 57
Area between z = − 2 and z = ∞
= Area between z = − 1 and z = 0 +
Area between z = 0 and z = ∞
=0.02275+0.5= 0.52275
Therefore number of fish having teeth greater than 57 cm
= 0.52275*480 = 5.2275*48 = 250.92 ≅251
