The probability<span> of an event is the measure of the chance that the event will occur as a result of an experiment. The </span>probability<span> of an event A is the number of ways event A can occur divided by the total number of possible outcomes.
a.) since each coin has 50% chance to have heads
(1/2) x (1/2) = 1/4 probability </span><span>The penny and nickel shows head
b.) </span><span>All these coins land the same way
</span>(1/2) x (1/2) x (1/2) = 1/8

Answer:
-3.125
Step-by-step explanation:
multiply -3*8 to get -24/8 then add the numerator -1/8+-24/8 to get -25/8 then convert by dividing -25/-8 to get -3.125
Answer:
Start by subtracting 3t from both sides of your equation
13t+4=12+3t
-3t. -3t
that gives you
10t+4=12
Subtract 4 from both sides
10t+4=12
-4. -4
That gives you
10t=8
Divide both sides by 10 to leave the variable by itself
10t=8
÷10. ÷10
That leaves you with
t=8/10 or t= 4/5 if you simplify.
Step-by-step explanation:
C ÷ D- EXPRESSION
-24÷1/4=-18
24
- 6
---------
18
The answer is negative because when you divide 24 by 4 you get 6. and since the number 24 is negative.you need to subtract 6 from 24 to get -18 which is negative.
P.S:I am a 6th graders who doesn't really understand negatives, but i tried my best and got this answer.
