We start with the formula for the probability of the union of two events:
$$
P(E \text{ or } F) = P(E) + P(F) - P(E \text{ and } F)
$$

Substitute the given values:
$$
P(E \text{ or } F) = 0.25 + 0.35 - 0.15
$$

Perform the calculation:
$$
0.25 + 0.35 = 0.60
$$
$$
0.60 - 0.15 = 0.45
$$

Thus, the probability is:
$$
P(E \text{ or } F) = 0.45
$$
$$ P(E \text{ or } F) = 0.45 $$

Find the probability of the indicated event if \( P(E)=0.25 \) and \( P(F)=0.35 \). Find \( P(E \) or \( F) \) if \( P(E \) and \( F)=0.15 \). \( P(E \) or \( F)=\square \) (Simplify your answer.)
