a. P(2 or 4) is the probability of rolling either a 2 or a 4 on the die.
P(2 or 4) is equal to P(rolling a 2) + P(rolling a 4)
1/6 + 1/6 = 2/6 = 1/3
b. P(greater than 2) is equal to P(3) + P(4) + P(5) + P(6)
1/6 + 1/6 + 1/6 + 1/6 = 4/6 = 2/3
7. The probability of getting a head is 1/2. If you toss the coin two times, there are four different possibilities. HH, TT, HT, or TH. The answer would be 1/4, you get that by multiplying 1/2 by 1/2 again.
Answer:
x=22
Step-by-step explanation:
x-10=12
add 10 to each side..
x-10=12
+10 +10
12+10=22
x=22
im bad at explaining but hope it helps <3
The value of -2−(−10) in a addtition expression is 8.
<h3>What is an expression?</h3>
Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.
Addition, subtraction, multiplication, and division are all possible mathematical operations. As an illustration, the expression x + y has the terms x and y with an addition operator between them.
In this case, -2 - (-10) will be:
= -2 -(-10)
= -2 + 10
= 8
The value is 8.

Answer:
Option B) (1, −4)
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the solid line 
Remember that
If a ordered pair is in the solution set of the inequality, then the ordered pair must lie in the shaded area of the solution
using a graphing tool
Plot the points
see the attached figure
Only the point B lie on the shaded area of the solution
therefore
The ordered pair (1, −4) is in the solution set
