Consider the following experiment: triplets are born and the order of birth of boys and girls is recorded. let the event a be: less than 2 children among triplets are boys and the event b be: more than 2 childrenamong triplets are boys. is the event b the compliment of the event a?

No, event B is not complement of event A.

Step-by-step explanation:

Event B is not a compliment of Event A because in complement we consider all those outcomes of the event which we don't want.If those outcomes match with the outcomes of the other event then we consider it as a complement of other event.Here in this case the outcomes which we don't want are not the complement of the outcomes of the other event.

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
