Answer:

Bronze = \frac{1}{4}

Step-by-step explanation:

Given

Gold = \frac{5}{12}

Silver = \frac{1}{3}

Required

Determine the probability of Bronze medal

In probability, sum is always equal to 1

i.e.

Gold + Silver + Bronze = 1

Make Bronze the subject

Bronze = 1 - Gold - Silver

Substitute values for Gold and Silver

Bronze = 1 - \frac{5}{12} - \frac{1}{3}

Take LCM

Bronze = \frac{12 - 5 - 4}{12}

Bronze = \frac{3}{12}

Bronze = \frac{1}{4}

Hence:

The probability of picking bronze is

Bronze = \frac{1}{4}
