Q. Given that events A and B are independent with P(A)=0.72 P(A)=0.72 and P(B)=0.1 P(B)=0.1 , determine the value of P(AB) P(A \cap B) , rounding to the nearest thousandth, if necessary.\newlineAnswer:
  1. Understand concept of independent events: Understand the concept of independent events. For independent events AA and BB, the probability of both events occurring together, denoted as P(AB)P(A \cap B), is the product of their individual probabilities. P(AB)=P(A)×P(B)P(A \cap B) = P(A) \times P(B)
  2. Substitute given probabilities into formula: Substitute the given probabilities into the formula. \newlineP(A)=0.72P(A) = 0.72\newlineP(B)=0.1P(B) = 0.1\newlineP(AB)=0.72×0.1P(A \cap B) = 0.72 \times 0.1
  3. Calculate product to find P(AB)P(A \cap B): Calculate the product to find P(AB)P(A \cap B).P(AB)=0.72×0.1=0.072P(A \cap B) = 0.72 \times 0.1 = 0.072
  4. Round result if necessary: Round the result to the nearest thousandth if necessary.\newlineThe result is already at the thousandth place, so no further rounding is needed.
