2. According to the Center for Disease Control, about 1 in 80 children in the U. S. have been diagnosed with autism. Suppose you consider a group of 10 children. Find the probability that: a) None have autism; b) 4 have autism; c) at least 2 has autism.

(a) 88.18%

               (b) 0.00000226%

               (c) 10.7%

Step-by-step explanation:

a) 0 "Have Autism" and 10 "Don't have Autism"

    (0.0125)⁰ (0.09875)¹⁰ = 0.8818    

                                        = 81.18%

b) 4 "Have Autism" and 6 "Don't have Autism"

    (0.0125)⁴ (0.9875)⁶ = 0.0000000226

                                     = 0.00000226%

c) 2 (or more) Have Autism and 8 (or less) Don't Have Autism

It is best to find the opposite and subtract from 100%

0 "Have Autism" and 10 "Don't have Autism" = 0.8818 (see part a)

                             or

1 "Have Autism" and 9 "Don't have Autism" = (0.0125)¹ (0.9875)⁹

                                                                        = 0.0112

1 - (0.8818 + 0.0112) = 0.1070

                                 = 10.7%

step-by-step explanation:

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
