If there is 5/8 of a total fuel supply on board, the ship can make 6 round trips
<u>Solution:</u>
Let the number of the round trips the ships make be "n"
Now, according to question in one trip the ship consumes of its total fuel supply which is given to be
Fuel supply used in "1" trip =
Now fuel supply used for "n" trip is given as:
Hence the ship can make 6 round trips
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
