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

svlad2 [7]

Answer:

P = 0.000000028514

Step-by-step explanation:

First we are going to calculate the probability of correctly choosing exactly 4 of the winning numbers.

Remember that the probability of an event can be calculated thus:

P = \frac{favourable - cases}{total -cases}

The favorable cases resulting from choosing 4 numbers of the set of 5 winning numbers from the upper section.

The favorable cases can be calculated with a combinatorial thus:

5C4 = \frac{5!}{(5-4)!4!} =5

and the total cases are:

59C5 = \frac{59!}{(59-5)!5!} = 5006386

Then the probability is:

P = \frac{5}{5006386} = 0.000000998

and the probability of correctly choosing  the Mega Ball number is:

P = \frac{1}{35} = 0.0285714

And how both events are independent the probability of correctly choosing exactly 4 of the winning numbers and the Mega Ball number is:

P = (0.000000998)(0.0285714)

P = 0.000000028514
