Question

two events, a and b, are independent. if p(a) = 0.3 and p(b) = 0.2, what is p(a and b)?

Explanation:

Step1: Recall the formula for independent events

For two independent events \( A \) and \( B \), the probability of both \( A \) and \( B \) occurring is given by the formula \( P(A \text{ and } B)=P(A)\times P(B) \).

Step2: Substitute the given values

We know that \( P(A) = 0.3 \) and \( P(B)=0.2 \). Substituting these values into the formula, we get \( P(A \text{ and } B)=0.3\times0.2 \).

Step3: Calculate the product

\( 0.3\times0.2 = 0.06 \).

Answer:

\( 0.06 \)
