Answer 1

Step-by-step explanation:

Given,

Total no. of marbles = 45

Probability of choosing a blue marble = $\frac{2}{9}$

∴ No. of blue marbles = 45 × $\frac{2}{9}$

                                    = 10

So, the rest of the marbles should be red marbles.

∴ No. of red marbles = 45 - 10

                                   = 35 (Ans)
