Question

1. using the venn diagram shown, find:

6c ( p(a \text{ or } b) )
probability ( = \frac{6 + 7 + 13}{6 + 7 + 13 + 11} )
explain
probability ( = \frac{6 + 7 + 13}{6 + 7 + 13 + 11} )
probability ( = \frac{6 + 7 + 13}{6 + 7 + 13 + 11} )

Explanation:

Step1: Calculate numerator (A or B)

Sum values in A, B, and their intersection: \(6 + 7 + 13 = 26\)

Step2: Calculate denominator (total)

Sum all values in the sample space: \(6 + 7 + 13 + 11 = 37\)

Step3: Compute probability

\(P(A \text{ or } B) = \frac{26}{37}\)

Answer:

\(\frac{26}{37}\)
