Question

A real number between 2 and 8 will be picked according to the probability distribution shown in the figure. Regions under the curve are labeled A, B, C. The area of each region is shown in the table

Answer 1

Explanation:

Answer 2

`\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.

`P(4&6)=0.50`

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}`
