Answer:
See you have to draw three circles and then write all the contents in different ones
Answer:
F=21 S=13
In the down box =30
Step-by-step explanation:
100 is the total number of people in the sport centre
in Venn diagram they normally use the first letter i.e for example here we are given fitness suite that is the F and we are given swimming pool that is the S
57 use fitness suite, so, 57 is under F
49 use swimming pool, so, 49 is under S
the box outside the circle is those that neither use the fitness suite nor the swimming pool.
to get that number you need to calculate those that uses only the fitness suite= 57-36 = 21
and those that uses only the swimming pool = 49-36 = 13
now we add everything together = 21+ 36+ 13 = 70
Remember the total number is 100
so you minus those using the fitness suite and swimming pool and the both which is = 70 from the total number of people in a sport center which is = 100
i.e 100 - 70 =30
∴ the answer for the down box is = 30
