Answer:

P (A) = 0.45

Step-by-step explanation:

The addition rule of probability states that:

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

Given:

[tex]P(A\cup B) = 0.7\\P(A\cap B) = 0.1\\P(B) = 0.35[/tex]

Compute the value of P (A) as follows:

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)\\P(A)=P(A\cup B) + P(A\cap B) - P(B)\\= 0.7 +0.1-0.35\\=0.45[/tex]

Thus, the probability of A is, P (A) = 0.45.
