Answer:
12 burgers
Step-by-step explanation:
Let Jolly had x burgers. If he eats two burgers then remaining burgers = (x-2)
Now he divides these remaining burgers among his five friends. Then each friend gets 2 burgers.
So the equation will be
We further simplify this equation to get the value of x.
(x-2) = 2 × 5
(x-2) = 10
x = 10 + 2
x = 12
Therefore, there were 12 burgers.

Answer:
(a) The value of fₓ (9.5) is 0.125.
(b) The value of fₓ (10.5) is 0.50.
Step-by-step explanation:
Let <em>X</em> denote delivery time of the mail delivered by Alice and <em>Y</em> denote delivery time of the mail delivered by Bob.
It i provided that:
The probability that Alice delivers the mail is, <em>p</em> = 1/4.
The probability that Bob delivers the mail is, <em>q</em> = 3/4.
The probability density function of a Uniform distribution with parameters [<em>a</em>, <em>b</em>] is:
The probability density function of the delivery time of Alice is:
The probability density function of the delivery time of Bob is:
(a)
Compute the value of fₓ (9.5) as follows:
For delivery time 9.5, only Alice can do the delivery because Bob delivers the mail in the time interval 10 to 12.
The value of fₓ (9.5) is:
Thus, the value of fₓ (9.5) is 0.125.
(b)
Compute the value of fₓ (10.5) as follows:
For delivery time 10.5, both Alice and Bob can do the delivery because Alice's delivery time is in the interval 9 to 11 and that of Bob's is in the time interval 10 to 12.
The value of fₓ (10.5) is:
Thus, the value of fₓ (10.5) is 0.50.
