Solution

The correct option is A

True


The total number of possible outcomes = Total number of marbles

                                                               = 4+ 8

                                                               = 12

Number of favourable outcomes = Number of red marbles

                                                    = 4

 Probability of getting a red marble = number of favourable outcomestotal number of outcomes

                                                          = 412

                                                          = 13
