Answer:
The expected value for the number of times Todd attends a concert during a month is 0.5.
Step-by-step explanation:
We have these following probabilities:
5% probability of attending a concert twice a month, which means that P(X = 2) = 0.05
40% probability of attending a concert once a month, which means that P(X = 1) = 0.4
55% probability of not attending a concert during the month, which means that P(X = 0) = 0.55
What is the expected value for the number of times Todd attends a concert during a month?
We multiply each value by its probability. So
The expected value for the number of times Todd attends a concert during a month is 0.5.
The process here is finding out the smallest number's % towards the largest number.
Divide 20 by 52:
20/52 = 0.38 (estimated) | This is the % in decimal form, which is 38%.
Conclusion: 20 is 38% of 52.

Finding the Smallest Number:
What number is 25% of 60?
Multiply 60 by the decimal form of 25%.
60 * 0.25 = 15 | 15 is 25% of 60.
Finding the Percentage. (Like what we already did.)
30 is what percent of 150?
Divide 30 by 150.
30/150 = 0.2 | 30 is 20% of 150.
Finding the Largest Number.
12 is 30% of what number?
Divide 12 by the decimal form of 30%.
12/0.3 = 40 | 12 is 30% of 40.
I hope this helps, have a great rest of your day! ^ ^

Well, i dont know if this helps but a tiger can eat about up to 50 pounds of meat a day. If you divide 1,754 by 50 then you will find your answer:D
