Calculate the probability of getting 3 heads when flipping 3 coins: penny, nickel, and dime.
No

three of them contain exactly two presidents, thus the probability of flipping exactly three heads is 3/8.

Step-by-step explanation:

give more details

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
