Question 1031504: Records show that a child of parents with heart disease has a probability of (fraction) 6/7 of inheriting the disease. Assuming independence, what is the probability that, for a couple with heart disease that have two children:
(a) Both children have heart disease. Enter the exact answer.
(b) Neither child has heart disease. Enter the exact answer.
(c) Exactly one child has heart disease. Enter the exact answer Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! There are 4 possible outcomes for two kids(Y-has heart disease, Z-does not have heart disease)
YY
YZ
ZY
ZZ
With the corresponding probability,
So,
a)
b)
c)
