Events:
1 ≤ n ≤ 100
A=x is a perfect square, i.e. x=n^2
B=x is odd, i.e. n is odd
P(A|B)
=P(A∩B)/P(B) by definition of conditional probability
(reads Probability that the number is a perfect square given that it is odd)
Since there are 10 perfect squares between 1 to 100 (1,4,9,16,25,36,49,64,81,100), out of which 5 are odd {1,9,25,49,81)
So P(A∩B)=5/100
P(B)=probability of odd x {1,3,5,7,.....95,97,99}
= 50/100=1/2
Therefore
P(A|B)=(5/100)/(1/2)=1/10

Answer:
87°
Step-by-step explanation:
The two marked angles are "vertical angles," so have the same measure. We can't read the number, but suspect it might be 87°. If so, then x° = 87°.
Answer:
32 times
Step-by-step explanation:
1/8 x 8= 1
1/8 x 32= 4
Since your total for the English book is 5, you make a ratio of
5:150
to make 5 equal 150, you multiply by 30. So if you multiply 3 by 30, you get 90, and 2 by 30 you get 60
60+90=150
new ratio- 90:60
or 90 pages of literature and 60 pages of grammar
