Answer:

P (x = 0)  1/16 = 0.0625

Step-by-step explanation:

We toss a fair coin 4 times.

HT HT HT HT      4/4   of each if TH TH TH TH etc..

HT HT HT TH     3/4

HT HT TH HT    3/4

HT HT TH TH    1/2

Let X count heads. Find P(X = 0) to nearest ten thousandth (4 decimal places).

P (x = 0)  1/16 = 0.0625

We cna find the average by multiplying a midpoint on one half findings on one side ie) 4/4 x 3/4 x 3/4 x 1/2  = 0.2813

Answer:

Step-by-step explanation:

If you toss the coin 4 times, you get 2 * 2 * 2 * 2 possible outcomes, which is 16 outcomes.

There is only 1 outcome where P(x = 0) is possible and that would be

T T T T

one out of 16 is .0625. So

Answer: P(x = 0 )  = 0.0625

erik [133]

Answer:

C) 2/5×1/4

Dividing by a number is the same by multiplying by the reciprocal of the number.

For Example:

1/2 divided by 3 would be the same as 1/2 x 1/3

So for this problem we are given that 2/5 is divided by 4 which would be the same as 2/5 multiplied by the reciprocal of 4 which is 1/4 and thus the answer is option C which is 2/5×1/4
