Bonjour j'ai un dm de maths écris en anglais que je dois rendre (en français) , si vous pouvez m'aider à répondre aux questions svp :
A clock stops at random. The random variable X is the position of the hour hand after it has stopped, expressed as a real number.
a) give the probability density of the variable X, and sketch its graph.
b) compute the probability that the hand is between 3 o'clock and 7 o'clock.
c) the hand has stopped between 12 o'clock and 6 o'clock. Compute the probability that it has stopped between 2 o'clock and 4 o'clock.
