Step-by-step explanation:

Answer: The probability that a gene is of type A is 0.29.
Step-by-step explanation:
Let A be the event of type A.
Let B be the event of type B.
Let D be the event of dominant.
So, P(B and D) = 0.22
P(D|B)=0.31
So, Using the conditional probability, we get that

So, the probability that a gene is of type A is given by

Hence, the probability that a gene is of type A is 0.29.
First calculate the total
8 bags x 3.5 cups=28 cups total
28 cups/ 12 hikers = 2.33
Each hiker will receive 2 and 1/3 cups of trail mix
Answer:you do 5x13 which equals 65 then 9+15 which equals 24 so 24=65
