Answer:
The probability that event B will occur is 0.45
Step-by-step explanation:
Given;
probability that event A occurs, P(A) = 0.4
the probability that events A and B both occur, P(A ∩ B) = 0.25
the probability that either event A or event B occurs, P(A ∪ B) = 0.6
To determine the probability that event B will occur, we use probability addition rule;
P(A) + P(B) = P(A ∩ B) + P(A ∪ B)
0.4 + P(B) = 0.25 + 0.6
0.4 + P(B) = 0.85
P(B) = 0.85 - 0.4
P(B) = 0.45
Therefore, the probability that event B will occur is 0.45

Question 4 How many integer numbers between 0 and 9999 are there that have exactly one digit 1 and exactly one digit 3
Answer:
768 numbers
Step-by-step explanation:
Given
[tex]Digits = \{0,1,2,3,4,5,6,7,8,9\}[/tex]
Required
Number of digits between 0 ad 9999 that have one 1 and one 3
There are a total of 4 digits that make up any of the numbers in 0 to 9999 with the given condition
This can be represented as WXYZ
Digit 1 can occupy any of the 4 positionsDigit 3 can occupy any of the 4 - 1 positionsThe remaining 8 digits will occupy the last 2 positions in the following ways:
The first of the 8 digits can be selected from any of [tex]\{0,2,4,5,6,7,8,9\}[/tex] i.e. 8 waysThe second can be selected from any of [tex]\{0,2,4,5,6,7,8,9\}[/tex] i.e. 8 waysSo, the total number of selection is:
[tex]Total = 4 * (4 - 1) * 8 * 8[/tex]
[tex]Total = 4 * 3 * 8 * 8[/tex]
[tex]Total = 768[/tex]

The point which is the solution of the inequality y ≤ 2x - 4 is,
⇒ (3, 2)
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
We have to given that;
The inequality is,
⇒ y ≤ 2x - 4
Now, From the options;
Option 3;
Point = (3, 2)
Put x = 3, y = 2;
⇒ y ≤ 2x - 4
⇒ 2 ≤ 2 × 3 - 4
⇒ 2 ≤ 6 - 4
⇒ 2 ≤ 2
Thus, The point which is the solution of the inequality y ≤ 2x - 4 is,
⇒ (3, 2)

Find the maximum value of
P = x + 6y
subject to the following constraints:
(2x + 4y < 10
X + 9y < 12
x > 0
y0
P = [?]
Answer:
(3, 1)
Step-by-step explanation:
Given the following constraints:
2x + 4y ≤ 10
x + 9y ≤ 12
x ≥ 0
y ≥ 0
We have to first graph the above constraints and secondly, we find the boundary points for the feasible region. This is done by plotting the graphs of 2x + 4y ≤ 10 and x + 9y ≤ 12.
From the graph, the following points satisfy the constraints:
(0,0) , (3,1) , (0,4/3) , (5,0)
Given that:
P = x + 6y
For (0, 0): P = x + 6y = 0 + 6(0) = 0
For (3, 1): P = x + 6y = 3 + 6(1) = 9
For (0, 4/3) P = x + 6y = 0 + 6(4/3) = 8
For (5, 0) P = x + 6y = 5 + 6(0) = 5
