To find $P(B)$, we can use the formula for the probability of the union of two events $A$ and $B$:

$P(A \text{ or } B) = P(A) + P(B) - P(A \text{ and } B)$

Given:

• $P(A \text{ or } B)$
• $P(A)$
• $P(A \text{ and } B)$

We can rearrange this formula to solve for $P(B)$:

$P(B) = P(A \text{ or } B) - P(A) + P(A \text{ and } B)$

Plug in the values once provided, and then simplify the result.

Please provide the values for $P(A \text{ or } B)$, $P(A)$, and $P(A \text{ and } B)$ so we can continue.
