从已知的ξ ~ b (3,34),
p(ξ= 0)= C03(14)3 = 164,
p(ξ= 1)= c 13(34)(14)2 = 964,
P(ξ=2)=C23(34)2(14)=2764,
P(ξ=3)=C33(34)3=2764,
∴ξdistribution的名单是:
?ξ?0?1?2?3?p?164?964?2764?2764
p(ξ= 0)= C03(14)3 = 164,
p(ξ= 1)= c 13(34)(14)2 = 964,
P(ξ=2)=C23(34)2(14)=2764,
P(ξ=3)=C33(34)3=2764,
∴ξdistribution的名单是:
?ξ?0?1?2?3?p?164?964?2764?2764
