The probabilities of selecting each colour are shown below.
Red = 6x
Green = 2x
Brown = x
Yellow = 4x
Find the probability of selecting a brown marble.

Respuesta :

Brown = 2x because of the equation done

The probability of selecting a brown marble is 1 / 13.

What is probability?

It's a field of mathematics that studies the probability of a random event occurring. From 0 to 1, the value is expressed.

Probability of picking a red marble = 6x

Probability of picking a green marble = 2x

Probability of picking a brown marble = x

Probability of picking a yellow marble = 4x

Sum of all probabilities = 1

(6x + 2x + x + 4x) = 1

13x = 1

x = 1 / 13

Hence the probability of picking a brown marble is 1 / 13.
