can i ask a question about probability?
the question is this:

A shop sells ice cream in three flavors: chocolate, strawberry and vanilla.One day, the shop owner notes the following information:

100 people entered the shop
9 people bought no ice cream at all
60 chocolate ice creams were sold
17 people bought only strawberry ice creams
11 people bought both chocolate and strawberry( 6 of whom also bouhgt vanilla)
76 people did not buy vanilla ice creams

The same number of people bought both chocolate and vanilla as bought both straberry and vanilla..

i need to draw venn diagram for this problem then solve the equation

thanks in advance for your response
