Find the probability that less than 6 patients experienced dizziness.
X ~ Binomial(15, 0.45)
P(X < 6) = sum%28%28matrix%282%2C1%2C15%2Cx%29%29%280.45%5Ex%29%280.55%5E%2815+-+x%29%29%2Cx+=+0%2C5%29 = highlight%280.26076%29

Find the probability that at least 7 patients experienced dizziness.
X ~ Binomial(15, 0.45)
P(X ≥ 7) = = highlight%280.54784%29

Find the probability that at most 4 patients did NOT experience dizziness.
X ~ Binomial(15, 0.55)
P(X ≤ 4) = sum%28%28matrix%282%2C1%2C15%2Cx%29%29%280.55%5Ex%29%280.45%5E%2815+-+x%29%29%2Cx+=+0%2C4%29 = highlight%280.02547%29
