Answer:
Step-by-step explanation:
given that we have an urn with m green balls and n yellow balls. Two balls are drawn at random.
a) Assume that the balls are sampled without replacement.
m green and n yellow balls
For 2 balls to be drawn at the same colour
no of ways = either 2 green or 2 blue = mC2+nC2
Total no of ways = (m+n)C2
Prob =
=
=
B) Assume that the balls are sampled with replacement
In this case, probability for any draw for yellow or green will be constant as
n/M+n or m/m+n respectively
Reqd prob =
=
c) Part B prob will be more than part a because with replacement prob is more than without replacement.
II time drawing same colour changes to m-1/.(m+n-1) if with replacement but same as m/(m+n) without replacement
Since n>0 is true always, b is greater than a.
Answer:
c = 116
Step-by-step explanation:
c and 64 are same- side interior angles and supplementary, thus
c + 64 = 180 ( subtract 64 from both sides )
c = 116
Answer:
Step-by-step explanation:
1. asks you to add the two functions and , which would be
Simplify the like-terms and you get:
------------------
2. asks you to multiply the two functions and , which would be
In order to multiply the functions we use the FOIL method (for polynomials):
Multiply each term and you get:
Simplify the like-terms and you get:
------------------
3. asks for your ability to understand what composite functions are. In order to solve this, we will follow some careful steps and solve them separately.

Now that we have both values, we can just subtract them:
100000000+10000000+9000000+3= 119000003
Answer is : f^-1 (x)=-2x/3+1
