Answer:
the probability of having a widow peak and attached earlobe = 0.6667*0.66667 = 0.4445 = 44.5%
Step-by-step explanation:
Martha = widow's peak + attached earlobes.
Martha's dad = straight hairline + unattached earlobes.
Martha husband =straight hairline+ widow's peak + attached earlobes
what is the probability that Martha child will have a widow's peak + attached earlobes?
since,
Martha + Martha husband =straight hairline+ widow's peak + attached earlobes
the probability of the child having widow peak is 2/3 = 0.6667
the probability of the child having attached earlobes is 2/3 = 0.66667
the probability of having both = 0.6667*0.66667 = 0.4445

What does the base of the grassy area look like?
Answer:
A: They are independent because P(X). P(Y) = PIX and Y).
Step-by-step explanation:
A) Two events X and Y are said to be independent if the probability of X occurring does not affect the probability of Y occurring or the probability of Y occurring does not affect the probability of X occurring. An example of independent events is the rolling of a die and flipping of a coin because the probability of getting a face in the die does not influence the probability of getting a head or tail in the coin. The probability of both events occurring is given as:
P(X and Y) = P(X).P(Y)
