In a bag there are 13 red marbles, 15 green marbles and 32 blue marbles. What is the probability of NOT picking a green marble.
Reduce fraction to lowest terms.

45:15 turned into a fraction =1/3

Step-by-step explanation:

3/4

Step-by-step explanation:

Total sample space(S)=60

Probability of red marbles(PR)= 13/60

Probability of green marbles(PG)=15/60

Probability of blue marbles(PB)=32/60

Solution,

Probability of not getting green marble(P-G)=1-15/60

                                                                            =1-1/4

                                                                            = 3/4
