The area is 10 just use a area calculator!
Answer:
Step-by-step explanation:
Total number of marbles = 5 + 2 + 3 = 10
Probability of choosing 1 green marble = 2/10
Probability of choosing 1 yellow marble = 3/10
Notice (and this is important) that the denominator didn't change. Why?
Because you replaced the first marble into the bag. That word replacement is critical in a problem of this nature. There is the term non replacement which means that the second draw would have a denominator of 9.
So what is the probability of P(green then yellow)?
P(green then yellow) = 3/10 * 2/10 = 6/100
Answer: P(green then yellow) = 3/50 because 6 / 100 reduces.

Answer:
10
Step-by-step explanation:
Given expression is 
.
is a complex expression.
The value of<em> i </em>is –1.
By definition of absolute value, 
Now, substitute in the above formula.
(since <em>i </em>= –1)
(since 
and 
)
(Square root of 100 is 10)
= 10
Hence, the value of the expression is 10.
