Ajar contains four coins: a nickel, a dime, a quarter, and a half-dollar. three coins are randomly selected from the jar. (a) what is the probability that the selection will contain the half-dollar? (enter an exact number as an integer, fraction, or decimal.)

The probability that the selection will contain the half-dollar is 3/4.

Step-by-step explanation:

Consider the provided information.

A jar contains four coins: a nickel, a dime, a quarter, and a half-dollar.

Three coins are randomly selected from the jar.

Let N represents nickel, D for dime, Q for quarter and H for half dollar.

The number of possible choices are:

Now we need to find the probability that the selection will contain the half-dollar.

P(choose a half-dollar) =

P(choose a half-dollar) =

P(choose a half-dollar) =

Hence, the probability that the selection will contain the half-dollar is 3/4.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
