A bag contains 8 purple marbles & 12 green marbles. You choose one marble out of the bag without looking.

What is the probability that you choose a purple marble.

What is the probability of you choosing a green marble

1. P (P) = 8/20 = 0.4

2. P (G) = 12/20 = 0.6

Step-by-step explanation:

Given;

Number of green marbles G = 12

Number of purple marbles P = 8

Total T = 12+8 = 20

The probability that you choose a purple marble P (P) is;

P (P) = number of purple marbles/total number of marbles

P (P) = P/T = 8/20 = 0.4

P (P) = 0.4

The probability that you choose a Green marble P (G) is;

P (G) = number of Green marbles/total number of marbles

P (G) = G/T = 12/20 = 0.6

P (G) = 0.6
