A study was carried out to determine the number of women using folic acid supplements in early pregnancy. All women attending a public or private clinic in Ohio were invited to participate and 28 women accepted. Based on previous studies, we know that typically 62% of pregnant women take folic acid supplements during early pregnancy.
a) What is the probability that exactly 25 women take a folic acid supplement during early pregnancy? (Use formula/show work, NOT binompdf or binomcdf.)
b) What is the probability that more than 21 women take folic acid supplements using early pregnancy? (Use binomcdf or binompdf. State function and its arguments.)
c) What is the probability that at least 15, but less than 20 women take folic acid supplements during early pregnancy? (Use binomcdf or binompdf. State function and its arguments.)
