Question

48 ice-creams are placed on a table. Some are chocolate flavoured and others are vanilla flavoured. If a person takes an ice-cream at random from the table, the probability that it is chocolate flavoured is $\frac{2}{3}$. Find the number of vanilla flavoured ice-creams on the table.

• A. 16
• B. 32
• C. 8
• D. 24

Answer 1

The correct option is A

16

We know that probability of picking a chocolate flavoured ice-cream will be $\frac{\text{Number of favourable outcomes ( chocolate flavoured icecreams)}}{\text{Total number of ice-creams}}$

Let the number of chocolate flavoured ice-creams be $x$.

= $\frac{x}{48}$ = $\frac{2}{3}$

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
= 16
