Answer
a)0.044
b)0.055
c)result from b)
d)No.
Work Step by Step
a) From the table, the probability of getting exactly 8 girls is: $P(X=8)=0.044.$
b)From the table, the probability of getting at least 8 girls is: $P(X\geq8)=P(X=8)+P(X=9)+P(X=10)=0.044+0.01+0.001=0.055.$
c)The result from b) because it gives us the probability for the range of 8 to 10 whilst a) only gives us the probability of 8.
d) 8 is not an unusually high number of girls, because 0.055>0.05.
