There are 10 forms on a desk. 6 of these are Type A forms, and the other four are Type B forms.

Suppose only 4 forms can be processed in one day. If these four are randomly selected one by one, what is the probability that:

a) exactly two forms from each of the two types are selected for processing?
b) each succeeding form is of a different type from its precessor

If 6 of these forms can be selected in one day,

Solutions

Expert Solution

a) from hypergeometric distribution probability that exactly two forms from each of the two types are selected for processing = =0.4286

b)total numebr of arrangent =N(all 4 are type A +3 of type A and 1 of type B+2 of type A and 2 of type B+1 of type A and 3 of type B+0 of type A and 4 of type B)

=4!/(0!*4!)+4!/(1!*3!)+4!/(2!*2!)+4!/(3!*1!)+4!/(4!*0!) =16

numebr of ways to arrnage forms so that each succeeding form is of a different type from its precessor

=N(ABAB or BABA) =2

hence probability =2/16 =1/8 =0.125

probability that only one of the two types of forms remains on his desk

=P(sleecting 2 of form A and 4 of form B+selecting all 6 of form A)

= =0.0714+0.0048 =0.0762
