A certain drug treatment cures 90% of cases of hookworm in children.18 Suppose that 20 children suffer- ing from hookworm are to

Anni [7]

Answer:

Step-by-step explanation:

Here X the no of children suffering from hookworm treated and recovered is binomial because

a) Each child is independent of the other

b) There are only two outcomes

c) The probability for any child to recover is constant as 90% = 0.9

X is Bin (20,0.9)

a) Prob that all 20 will be cured

=P(X=20)= $0.9^{20} \\=0.1216$

b) Prob all but 1 will be cured= $P(x=1) = 20C1 (0.9) (.1)^{19} \\=1.8(10^8)$

c) Prob exactly 18 will be cured

$=P(X=18)\\=20C18 (0.9)^{18} (0.1)^2\\= 0.2852$

d) Prob exactly 90% will be cured.

= $P(X=18)\\=20C18 (0.9)^{18} (0.1)^2\\= 0.2852$

Each basket at the farm stand holds 3 pounds of potatoes or 6 pounds of tomatoes. If there are 21 pounds of potatoes and 6 pound

jolli1 [7]

Answer:

8 baskets

Step-by-step explanation:

Well, we can simply divide each number by the amount of vegetables are needed.

6/6=1. We only need 1 basket for tomatoes.

21/3=7. We need 7 baskets for potatoes.

7+1=8 We need 8 total baskets.

Hope this helps! :D
