Probability Assignment Solution A die is thrown – Prime Number & Number Greater Than 4
Understanding the Problem • A standard die has 6 faces numbered 1 to 6. • Formula: P(E) = Favourable Outcomes / Total Outcomes • Total number of outcomes = 6
Case (i): Prime Number • Prime numbers between 1 and 6: 2, 3, 5 • Favourable outcomes = 3 • Total outcomes = 6 • P(Prime Number) = 3/6 = 1/2
Case (ii): Number Greater Than 4 • Numbers greater than 4 on a die: 5, 6 • Favourable outcomes = 2 • Total outcomes = 6 • P(Number > 4) = 2/6 = 1/3
Final Answer • 1. Probability of getting a prime number = 1/2 • 2. Probability of getting a number greater than 4 = 1/3
