ANSWER

$\begin{gathered} 1)0.50 \\ 2)0.70 \end{gathered}$

EXPLANATION

1) The Probability that a real number between 4 and 6 was picked is the area under region B.

2) The probability of picking a real number between 4 and 8 corresponds to the area under region B and C.

$\begin{gathered} P(4&8)=P(C)+P(C) \\ =0.5+0.2 \\ =0.7 \end{gathered}$
