Question

Picking a purple marble from a jar with 3 green and 3 purple marbles. What is the probability of picking a purple marble?

Answer 1

1/2

Explanation:

The total number of marbles in the jar is equal to 6

Since we have 3 purple marbles and 3 green marbles,

The probability of picking a purple marble =

Number of purple marbles in the jar / total number of marbles

= 3/6

= 1/2

From this calculation the probability of picking a purple marble is 1/2 or 0.5
