Answer:
Step-by-step explanation:
P(2 heads) = P(first flip = head)*P(second flip = head)
=> =
P(1 head) = P(first flip = head)*P(second flip = tail) + P(first flip = tail)*P(second flip = head)
=
P(no heads) = P(first flip = tail)*P(second flip = tail)
=
E(winning) =

Answer:
x = -14
Step-by-step explanation:
-3.5 = x/4
In the right side, the fraction x/4 means x divided by 4. We want x alone, so we multiply both sides by 4.
-3.5 * 4 = x/4 * 4
-14 = x
Answer: x = -14
Answer:
Bigger size / smaller size = 40

Bigger size / smaller size = 40
The total purchase price including sales tax will be $1449.6136
<em><u>Explanation</u></em>
Festus bought a computer at $736.34, Apple iPad at $249.99 and a printer at $381.23
