5) The probability that a typist makes 0, 1, 2, 3, 4, or 5 mistakes on a page are, respectively 0.09, 0.11, 0.24, 0.21, 0.17, 0.05. What is the probability that the typist makes three or more

mistakes mistakes on a page.

0.43

Step-by-step explanation:

Formatting the Given data into a probability distribution table :

X : 0 __ 1 ___ 2 3 4 5

P(x) : _0.09_0.11 _ 0.24 _0.21 ___ 0.17 __ 0.05

Probability of making 3 or more mistakes :

P(x ≥ 3) = P(x = 3) + P(x = 4) + P(x = 5)

P(x ≥ 3) = 0.21 + 0.17 + 0.05

P(x ≥ 3) = 0.43
