You have a 1/2 chance of spinning an even number on the spinner, and a 1/2 chance of rolling an odd number on the die, 1/2 times 1/2 give you a 1/4 chance of doing both of those tasks.
Answer:
The answer is 28
Step-by-step explanation:
Since the total measurements of triangle corners are equal to 180
Then

You just multiply 450 by .18 and it'll give you the 18% you have to add to 450.
So the equation would look like:
450(.18)=81
Which you then add:
450+81= 531
So 531 is your total!
There are 17 members who are only in gymnastics, 7 who are only in chess, and 3 who are in both.
