We know that probability of picking a chocolate flavoured ice-cream will be Number of favourable outcomes ( chocolate flavoured icecreams)Total number of ice-creams
Let the number of chocolate flavoured ice-creams be x.
= x48 = 23
Solving for x we get 32 .
It implies that there are 32 chocolate flavoured ice-cream out of 48
Hence number of Vanilla flavoured ice-creams on the table are:
= 48 - 32
