Answer:
a) 2/3
b) 1/3
Step-by-step explanation:
Let X be the random event that measures the time you will have to wait.
Since time is uniformly distributed between 10 and 10:30 in intervals of 1 minute
P(n < X ≤ n+1) = 1/30 for every minute n=0,1,...29.
a)
P( X > 10) = 1 - P(X ≤ 10) = 1 - 10/30 = 2/3
b)
P(10 < X ≤ 20) = (20-10)/30 = 1/3
Answer:
The answer to your question is B.
Magnitude = sqrt (4^2 + 4^2 + 1^2) = sqrt 33 Answer
Started out with 32/32. They ate 18/32, 32-18=14; 14/32. To simplify, 7/16 was left.
