<h3>
Answer: The value of P(A or B) is 0.8.</h3>
Step-by-step explanation: We are given P(A)=0.6 , P(B)=0.3 and P(A and B)=0.1.
P(A and B)=0.1 could be written as P(A∩B) = 0.1.
We need to find P(A or B) that is P(A∪B) = ?
We know formula,
P(A∪B) = P(A) + P(B) - P(A∩B)
Plugging values in formula, we get
P(A∪B) = 0.6 + 0.3 - 0.1
P(A∪B) = 0.9 -0.1
P(A∪B) = 0.8.
<h3>Therefore, the value of P(A or B) is 0.8.</h3>
