Two parents who are each known to be carriers of an autosomal recessive allele have four children. none of the children has the recessive condition. what is the probability that one or more of the children is a carrier of the recessive allele? hint: the probability that one or more of the children is a carrier is the same as the sum of all probabilities minus the probability that none of the children is a carrier.

Option A = 75 is the best option

Step-by-step explanation:

It took Ashlie 2.5 hours (11:30 am - 2pm) to assemble the marketing packets

Rate = Number of jobs done/Time taken = 90 packages/hr

Number of jobs done = Rate * Time taken = 90 * 2.5 = 225 packages.

Dwayne has assembled the same number of packages = 225 (as reported in the question),

It took Ashlie 2.5 hours (11 am - 2pm)

Then, his work rate is calculated as:  Number of jobs done/Time taken = 225 packages/3 hours = 75

Thus, option A = 75 is the best option
