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

B

Step-by-step explanation:

Expanding the factors using FOIL

A

(x - 3)(x + 4)

= x² + 4x - 3x - 12

= x² + x - 12 ← a trinomial

B

(x + 3)(x - 3)

= x² - 3x + 3x - 9

= x² - 9 ← a binomial

C

(x - 3)² = (x - 3)(x - 3) = x² - 6x + 9 ← a trinomial
