Answer:
15 times
Step-by-step explanation:
To find the expected count you have to multiply the probability of the favorable event with the number of repetitions/rolls. For a fair dice, every number will have the same probability to occur. The dice have number 1 to 6 which mean there are 3 odd numbers (2, 4, 6) out of 6 possible number.
Then the probability for odd number will be: 3/6= 1/2
The expected count of odd numbers in 30 rolls will be= 1/2 * 30 =15 times.
well, we know is 10% for the first 7500, but Dan only made 5000 of taxable income, so he's in that range of 0 - 7500, so he only gets to pay 10% of 5000.
