Question

1. using the venn diagram shown, find:

4c ( p(a \text{ or } b) )
probability ( = \frac{6 + 5 + 12}{6 + 5 + 12 + 8} )
explain

Explanation:

Step1: Calculate numerator (A or B)

Sum of regions in A or B: \(6 + 5 + 12 = 23\)

Step2: Calculate denominator (total)

Sum of all regions: \(6 + 5 + 12 + 8 = 31\)

Step3: Compute probability

\(P(A \text{ or } B) = \frac{23}{31}\)

Answer:

\(\frac{23}{31}\)
