Answer:
A. -10.21
Step-by-step explanation:
We know that he bought 3 sets of pencils for $30.63, so assuming each set costs the same amount, we divide 30.63 (the total cost) by 3 (the number of sets purchased) which would give us 10.21. Because we know that this money would have been subtracted from his bank account, then we know that it is a negative number.
Meaning the final answer would be -10.21
About 31.5% when rounded.
This is because you have to start with the probability of each urn. The first urn has 13 total balls (5 white and 8 yellow). Since 5 of them are white, the odds of pulling a white ball are 5/13. Then find the same for the second urn (9 white and 2 yellow). Therefore there are 11 total balls and 9/11 chance of getting a white one. After finding both, multiply them together to get the answer.
