Answer:
a: 0.08, or 8% chance he wins all 3
b: 0.42, or 42% chance he wins 2
Step-by-step explanation:
P(win A) = 0.8
P(lose A) = 0.2
P(win B) = 0.5
P(lose B) = 0.5
P(win C) = 0.2
P(lose C) = 0.8
The situations are independent, so we multiply probabilities together.
To win all 3: P(win A)*P(win B)*P(win C) = 0.8*0.5*.02 = 0.08
To win 2 of the 3 there are 3 ways to do this. We add up the probabilities of the 3 situations...
P(win A)*P(win B)*(lose C) = 0.8*0.5*0.8 = 0.32
P(win A)*P(lose B)*P(win C) = 0.8*0.5*0.2 = 0.08
P(lose A)*P(win B)*P(win C) = 0.2*0.5*.02 = 0.02
0.32 + 0.08 + 0.02 = 0.42
Hello!
To solve this equation, we will need to use PEMDAS (parentheses, then exponents, then multiplication/division, then addition/subtraction).
7(3) + (-9) x (-4) =
21 + (-9) x (-4) =
21 + 36 =
57
I hope this helps you! Have a lovely day!

Answer:
-4 i think
Step-by-step explanation:
divide -12 by 3 to get -4
Answer:
None of them are irrational.
Step-by-step explanation:
An Irrational Number is a real number that cannot be written as a simple fraction.
Therefore:
-4 can be written as -4/1
2/9 is already in fraction
8.26 can be written as 826/100
11 can be written as 11/1
None of them are irrational.
However numbers like
are irrational as they can not be represented as fractions.
