Answer:
Step-by-step explanation:
When you find mean, you must add all the numbers together then divide by the amount of numbers.
There are 10 numbers.
To find median, you have to either find the middle number or find the two numbers that makes it equal. Since this range set is even, we use the second option.
Divide by 2

Answer:
<h2>i) 3</h2><h2>ii) 5</h2>Step-by-step explanation:
Let H be the set of students who play Hokey
V be the set of students who play Volleyball
S be the set of students who play Soccer
======================================
card(volleyball only) = card(V) - [card(V∩H∩S) + card(V∩H only) + card(V∩S only)]
= 73 - [50 + (58-50) + (62-50)]
= 73 - [50 + 8 + 12]
= 73 - 70
= 3
………………………………………………
Card(Hokey only) = 100 - [3 + 8 + 50 + 10 + 12 + 12]
= 100 - 95
= 5
