Finding probability with percentages
WebDec 13, 2024 · P(A B) is the probability of rain occurring given the cloudy morning – this is what we want to calculate. Similarly P(B A) is the probability of clouds on a rainy day – 60% or 0.6. P(A B) = [0.6 × 0.2] / 0.45) ≈ 0.27. In this case, the probability of rain occurring provided that the day started with clouds equals about 0.27 or 27%. WebTo find the probability on R, R always gives the probability to the left of the value. Looking at the figure, you can see the area you want is to the left. The command looks like: P ( x < 250) = pnorm ( 250, 272, 9) = 0.0073 Thus 0.73% of all pregnancies last less than 250 days. This is unusual since the probability is less than 5%. d.
