Assume the prior probability of having a female child is the same as having a malechild, both are 0.5. The Wood family has two kids, and you heard that at least one ofthem is a girl. What is the chance that the Wood family has a boy?

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

24,18t
