What's the probability a number is odd given that it's an integer between 0 and 11?

A odd number lie between 0 and 11(0 and 11 not included), it means that total of ten numbers, starting from {1,2,3,10} form our sample space.

sample space=s={1,2,3,10}=total 10 numbers
So,
m=total no. of odd numbers{1,3,5,7,9} in our sample space=5 numbers
 
probability that number is odd=p=m/s
p=5/10=0.5
  

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.

10 will be the number of adult tickets and 11 will be the number of children tickets. i hope i could ! good luck : )
