A person with type A blood can donate red blood cells to people with type A or type AB blood. About 31% of the US population has type A blood. You are asked to design a simulation to determine the probability that at least 4 of 10 people will have type A blood. Part A: Conduct five trials using the following table of random digits: (5 points)

96299 07196 98642 20639 23185 56282 69929 14125 38872 94168
71622 35940 81807 59225 18192 08710 80777 84395 69563 86280
03272 41230 81739 74797 70406 18564 69273 72532 78340 36699
46376 58596 14365 63685 56555 42974 72944 96463 63530 24152
47352 04266 74017 79319 70170 96572 08523 56025 89077 57678

Part B: Based on your simulation, what is the probability that at LEAST 4 of 10 people will have type A blood? (5 points) (10 points)

Please walk me through how you did this!

idk

step-by-step explanation:

use that smart brain

umm im not really sure because i never had to do this

step-by-step explanation:

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
