Answer:
-10
Step-by-step explanation:
First, evaluate the terms with exponents.
7-3²·9+4³

Multiply -9×9
7-81+64
Then, add or substract from left to right.
Your final answer is -10.
The probability of selecting a purple marble and then a white marble is 0.19.
The probability of selecting two white marbles is 0.03.
The probability of picking two purple marbles is greater.
Probability is used to determine the likelihood that an event would occur.
The probability of selecting a purple marble and then a white marble = (number of purple marbles / total number of marbles) x (number of white marbles / total number of marbles- 1)
7/9 x 2/8 = 0.19
The probability of selecting two white marbles = (number of white marbles / total number of marbles) X (number of white marbles / total number of marbles- 1)
2/9 X 1/8 = 0.03
The probability of selecting two purple marbles = 7/9 x 6/8 = 0.58
