Ignore the stupid people above.
(1/2)(1/2)(1/2)(1/2) = 1/16

Since each toss yeilds a 50/50% chance--and the coin is tossed four times--the correct answer is B, 1/4. The one represents the desired outcome, and the four represents the amount of tries used. If you tossed it sixteen times, the answer for having all tosses coming out "tails up" would be 1/16.

E- because you multiply 1/2 times 1/2 times 1/2 times 1/2 because each time you flip the coin there's a 1/2 chance of getting tails

1/2 X 1/2 X 1/2 X 1/2 = 1/16

A) 1/2.
If there are only two sides, head or tails, there's a 50/50 chance that it will land on tails, and vice versa!

Meh, That would be A-1/2. There is a 50-50 chance itll land on either side.

to figure this out you find the probability of each toss{ 1/2} and multiply them together 1/2x1/2x1/2x1/2 which equals 1/16 E
