2. explain whether the following statement is a valid definition: “a 150° angle is an obtuse angle.” use the converse, biconditional, and at least one euler diagram to support your answer.

Conditional: If the angle is 150°, then it is obtuse.

Converse: If the angle is obtuse, then it will equal 150°.

Biconditional: The angle is 150° if and only if it is obtuse

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
