A small deck of 5 cards consists of 3 red Jards and 2 green cards. Draw 7 times with replacement.
Find the probability that a red card is drawn exactly 3 times.

Approximately .

Step-by-step explanation:

The cards were drawn with replacement. Therefore, the probability of drawing a red card will be at every one of the seven draws. The probability of not drawing a red card would be .

One way to get three red cards out of the seven draws would be . That corresponds to a probability of .

However, there are many other ways to get three red cards during the seven draws. For example:

There are such ways in total to choose three draws out of seven draws.

These ways are mutually-exclusive. Each of these ways has a probability of . The probability for getting a red card on exactly three out of the seven draws would be:

.

12.4, 12.387, 12.26, 12.252, 6.241, 6.2, 6.015, 6.009, 1.411, 1.2, 1.056, 1.007, 0.31,   0.13, 0.5, 0.04

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
