In the report Congenital Anomalies in Canada 2013: A Perinatal Health Surveillance Report from public health agency of canada it is stated that approximately 1 in 25 babies born in canada is diagnosed with one or more congenital anomalies every year. the report focused mainly on Down syndrome, neural tube defects, congenital heart defects, oral facial clefts, limb deficiency defects and gastroschisis. we consider a sample of 100 newborn Canadian babies.

a) What is the propability that there will be at most two babies with a congenital anomaly in the sample ?

b) what is the expected number of babies in the sample with a congenital anomaly ?

c) what is the standard deviation of the number of babies with a congenital anomaly in the sample ?

this is what I did so far but i can't figure out the rest..
