4. Suppose that it is reported that 70% of workers aged 18 and over drive to work. Find the probability that more than 3 of the 10 workers chosen drive to work alone. Rounded off to 3 decimal places. Use the binomial distribution with n = 10 and p = 0.70. P(X > 3) = 1 − P(X ≤ 3) = 1 − P(0) – P(1) – P(2) – P(3) = 0.989

Transcribed Image Text:4. Suppose that it is reported that 70% of workers aged 18 and over drive to work. Find the
probability that more than 3 of the 10 workers chosen drive to work alone. Rounded off to 3
decimal places.
Use the binomial distribution with n = 10 and p = 0.70.
P(X > 3) = 1 – P(X ≤ 3) = 1 − P(0) – P(1) – P(2) – P(3) = 0.989
