Answer:
Each Pencil Cost 4 Dollars
Step-by-step explanation:
First you can subtract 21 by 9 to get 12 dollars which shows how much he spent.

Answer:
10y^3+6y
Step-by-step explanation:
The probability that he will be rejected to at least one of the colleges is 0.51.
Given probability that he will admit in A is 0.7, probability that he will not be admit in B is 0.5, probability that atleast one of his applications got rejected is 0.6.
We have to find the probability that he will be rejected to at least one of the colleges.
Probability that he will admit in A =0.7
Probability that he will not admit in A=1-0.7=0.3
Probability that he will not admit in B =0.5
Probability that he will admit in B=1-0.5=0.5
Probability that he will be rejected to at least one of the colleges=probability that he will admit in A* probability that he will not admit in B+ probability that he will admit in B* probability that he will not admit in A+ probability that he will not admit in A* probability that he will not admit in B
=0.7*0.5+0.5*0.3+0.5*0.3
=0.35+0.15+0.15
=0.51
Hence the probability that he will be rejected to at least one of the colleges is 0.51.

Answer:
The probability of the defendant is innocent given the defendant is convicted is P=0.006.
Step-by-step explanation:
Being:
G: guilty, I:innocent, C: convicted, A: acquitted.
We need to calculate P(I|C).
Being innocent, given convicted, is equal to the probability of being innocent and convicted divided by the probability of being convicted (innocent or guilty)
The probability of being innocent and convicted is
The probability of being convicted is equal to the sum of P(I&C) and P(G&C)
Then,
