In a pet shop there are 100 pets, out off which 50 are cross breed variety. What is the probability that a cross breed pet is selected when chosen randomly? Correct Answer <span class="math-tex">\(\frac{1}{2}\)</span>

Given:

Total pets = 100

Total cross breed variety pets = 50

Calculation:

Number of ways selecting a pet from 100 pets = 100C1

Number of ways selecting a pet of cross breed variety = 50C1

∴ Required probability = 50 C1/100C1 = 50/100 = 1/2
