Suppose that in Zambia, 42% of the population is of the O blood type. You choose three people at random from this population. Find the following probabilities (rounded to three decimals): a. All three of those sampled are type Of . Here we use the Multiplication Rule: P(All three are type Of ) = P(1st is O+ ) . P(2nd is O+ ) - P(3rd is 0 + ) = b. None of the three sampled are type Of . Here we use also me Multiplication Rule: P(None of the three sampled are type Of ) = P(1st is NOT O+ ) . P(2nd is NOT O+ ) . P(3rd is NOT 0 + ) = c. At least one of the three sampled is type Of . Here we use the Rule of Complements: P(At least one of the three sampled is type Of ) = 1 - P(None of the three sampled are type Of ) = Submit
