Use the identity P(A ∪ B) = P(A)+P(B)-P(A ∩ B)

P(A)=0.50
P(B)=0.60
P(A ∪ B) = 0.30
=>
P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
=(0.50+0.60)-0.30
=0.80

According to Hannah 2.11 is a rational number.

According to Gus 2.11 is a repeating decimal.

Please see..

2.11 don't have more dots after two ones after decimal.

<em>If it would be a repeating decimal, it should be look like this 2.11......</em>

<em>2.11 could be expressed as rational number 211/100.</em>

<h3>Therefore, Hannah is absolutely correct by saying hat 2.11 is a rational number.</h3>
