If a seed is planted, it has a 90% chance of growing into a healthy plant. If eleven seeds are planted, what is the probability that exactly four don't grow?
In the United States, 38% of the population has type A blood. Suppose 5 people from the U.S. are randomly chosen. Use the formula for binomial probabilities P(x)=nCz⋅p2⋅qn−x to find the probability that exactly 4 of the 5 people sampled have type A blood. (a) First fill in the details of the binomial probability formula: (b) The probability, accurate to 4 decimal places, is
Mrs. Walker filled out a bracket for the NCAA National Tournament. Based on her knowledge of college basketball, she has a 0.62 probability of guessing any one game correctly. The first answer you can express in scientific notation or as a decimal with at least three non-zero signficant digits. The second and last can be answered as decimals rounded to three places. What is the probability she will pick all 32 of the first round games correctly? What is the probability she will pick exactly 13 games correctly in the first round? What is the probability she will pick exactly 9 games incorrectly in the first round?
