Answer:
Part A:
The probability that all of the balls selected are white:

Part B:
The conditional probability that the die landed on 3 if all the balls selected are white:

Step-by-step explanation:
A is the event all balls are white.
D_i is the dice outcome.
Sine the die is fair:
for i∈{1,2,3,4,5,6}
In case of 10 black and 5 white balls:






Part A:
The probability that all of the balls selected are white:


Part B:
The conditional probability that the die landed on 3 if all the balls selected are white:
We have to find 
The data required is calculated above:

Step-by-step explanation:
a=3/4
Answer:
w = 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4(w+1)=−24
(−4)(w)+(−4)(1)=−24(Distribute)
−4w+−4=−24
−4w−4=−24
Step 2: Add 4 to both sides.
−4w−4+4=−24+4
−4w=−20
Step 3: Divide both sides by -4.
-4w/-4 = -20/-4
w=5
