Basketball shots are classified into $close-range,\;mid-range$ and  $long-range$ shots. Long range shots are worth $3$ points, while close-range and mid-range shots are worth $2$ points. Of the shots that LeBron James attempts, $45\%$ are close-range, $25\%$ are mid-range, and $30\%$ are long-range. He successfully makes $80\%$ of the close-range shots, $48\%$ of the mid-range shots, and $40\%$ of the long-range shots.

What is the probability that a LeBron shot attempt is successful?

  1. $\frac{1}{2}$
  2. $\frac{4}{5}$
  3. $\frac{3}{5}$
  4. $\frac{4}{7}$

Consider the following regular expressions over alphabet$\{a,b\}$, where the notation $(a+b)^+$ means $(a+b)(a+b)^*$: $r_1=(a+b)^+a(a+b)^*$ $r_2=(a+b)^*b(a+b)^+$ Let $L_1$ and $L_2$ be the languages defined by $r_1$ and $r_2$, respectively. Which of the following regular expressions define $L_1\cap L_2$ ... $(a+b)^*a\;b(a+b)^*$ $(a+b)^*b(a+b)^*a(a+b)^*$ $(a+b)^*a(a+b)^*b(a+b)^*$
