In a certain population, \( 15 \% \) of the people have Rh-negative blood. A blood bank serving this population receives 92 blood donors on a particular day. What is the probability that 10 or fewer are Rh-negative? (A) 0.1856 (B) 0.1658 (C) 0.1685 (D) 0.1865

What is the probability that 10 or fewer are Rh-negative? b. What is the probability that 15 to 20 (inclusive) of the donors are Rh-negative? c. What is the probability that more than 80 of the donors are Rh-positive?
The Normal Probability Distribution
The Normal Approximation to the Binomial Probability Distribution
In a certain population, 18% of the people have Rh-negative blood. A blood bank serving this population receives 96 blood donors on a particular day. (Use the normal approximation. Round your answers to four decimal places.) (a) What is the probability that 10 or fewer are Rh-negative? (b) What is the probability that 15 to 20 (inclusive) of the donors are Rh-negative? (c) What is the probability that more than 80 of the donors are Rh-positive?
