They each would pay 2.55
12.75 divided by 5 = 2.55
1.2 e⁻¹¹
Because you need a number between 1 and 10 for scientific notation. So you move the decimal over 11 places. Since you move it to the right, it becomes a negative exponent.
Answer:
0.0625
Step-by-step explanation:
The prevalence of gene a = 25 %, P (a) = 0.25
birth defect occurs when both parents have prevalence of gene a.
P (Defect) = P ( Both parents have gene a)
If both parents inherit the gene a independently, the the individual will have a birth defect when both parents have gene a.
P ( Father having gene a) = 0.25
P ( Mother having gene a) = 0.25
Hence,
P (Birth Defect) = P ( Both parents have gene a) = 0.25 * 0.25 = 0.0625
