If you would like to know the purchase price of Wilma's game, you can calculate this using the following steps:
15% of $43.89 = 15% * 43.89 = 15/100 * 43.89 = $6.5835 = $6.58
$43.89 - $6.58 = $37.31
5% of $37.31 = 5% * 37.31 = 5/100 * 37.31 = $1.8655 = $1.87
$37.31 - $1.87 = $35.44
The correct result would be <span>$35.44.</span>
The probability of picking red button is
<u>Solution:</u>
Given, A jar contains 30 red, 30 blue, and 60 white buttons.
You pick one button at a random choice,
We have to find the probability that it is red button.
Now, total number of buttons = 30 + 30 + 60 = 120 buttons.
Number of favourable cases for red button = 30 red buttons.
The probability of an event is given as:
Thus the probability that it is red is
