Step 1
From the given information,
O blood group -210,
A blood group -223,
B blood group -51,
AB blood group -16.
Step 2
The frequency distribution for the given data is shown below:
Blood typeFrequency0210A223B51AB16Total500
The probability that a randomly selected person from the population has neither type A nor type P is obtained as follows:
P(Neither Type A nor Type O)=1(P(Type A)+P(Type O))
=1(Number of favourable cases for blood type ATotal number of cases+Number of favorable cases for blood type OTotal number of cases)
=1(223500+210500)
=1(433500)
=67500
=0.134
