To find Shifaa's expected number of late arrivals in 4 weeks, we know she is late 2 days out of 6 each week. So, in one week, the expected number of days late is \( \frac{2}{6} \). Over 4 weeks, this becomes \( 4 \times \frac{2}{6} = \frac{8}{6} = \frac{4}{3} \) days. Thus, Shifaa is expected to be late around 1.33 days over those 4 weeks. For As'ha, she has a probability of 0.8 to score \( 100\% \) in each assessment. If she has a total of \( n \) assessments, the expected number of assessments where she scores \( 100\% \) is \( 0.8n \). For example, if she has 10 assessments, the expected number would be \( 0.8 \times 10 = 8 \) assessments where she is likely to achieve her target score!
