Answer 1

Answer:

The number of blue balls in the bag is 15.

Step-by-step explanation:

Let the total number of balls in the bag be, N.

The number of red balls is, 5.

Let the number of blue balls be x.

The probability of drawing a red ball is, $P(R)=\frac{5}{N}$.

The probability of drawing a blue ball is, $P(B)=\frac{x}{N}$.

It is provided that:

P (B) = 3 × P (R)

Solve this to determine the value of x as follows:

$\frac{x}{N}=3\times \frac{5}{N}\Rightarrow \frac{x}{N}=\frac{15}{N}\Rightarrow x=15$

Thus, the number of blue balls in the bag is 15.
