If P(A)=0.4, P(A and B)=0.2,and P(A or B)=0.5, What is P(B)

Vladimir [108]

Answer:

$\boxed{\ P(B)=0.3 \ }$

Step-by-step explanation:

Hi,

We know that

P(A or B)=P(A)+P(B)-P(A and B)

so P(B)= P(A or B) - P(A) + P(A and B)

P(B) = 0.5 - 0.4 + 0.2 = 0.3

|12| ÷ 2 • |-5|

Absolute values just make the number positive if it is negative. The number stays positive if it’s positive.
