or a large population of people, the probability distribution for the random variable X = the number of meals a person ate yesterday and the assigned probabilities is given below:
| Meals, X | 1 | 2 | 3 | 4 | 5 |
| Probability | 0.19 | 0.35 | 0.26 | 0.15 | ? |
a) Find P(X = 5), the probability that a
randomly selected person ate 5 meals yesterday.
P(X = 5) =
(b) Find P(X 2), the probability that
a randomly selected person ate 2 or fewer meals yesterday.
P(X 2) =
(c) Find the probability that a randomly selected person ate 1 meal
or ate 5 meals yesterday.
P =
(d) Find P(X > 1), the probability that a
randomly selected person ate more than 1 meal yesterday.
P(X > 1) =
