Acertain medical test is known to detect 72% of the people who are afflicted with the disease y. if 10 people with the disease are administered the test, what is the probability that the test will show that: all 10 have the disease, rounded to four decimal places? at least 8 have the disease, rounded to four decimal places? at most 4 have the disease, rounded to four decimal places?

10773

Step-by-step explanation:

.75^10=0.0563

look at 8, 9, 10

8 the probability is 10C8*0.75^8*0.25^2=0.2816

9 the probability is 0.1877 using the same approach

At least 8 is 0.5256  

At most 4 is  

0 .25^10=essentially 0

1: 10C1*0.75*0.25^9=<0.0001

2: 45*0.75^2*0.25^8=0.0004

3: 120*0.75^3*0.25^7=0.0031

4: 10C4*0.75^4*0.25^6=0.0162

That sum is 0.0197

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
