We can express that probability as P(V | W), the probability of V given W.
Step-by-step explanation:
We know that the chosen person works for the goverment, so we have to assume W as hypothesis. Therefore, in order to calculate the probability of that person voting on the election, event noted by V, we have to <em>condition</em> V to the event W. As a result, we want the probability of V given W, which can be written as P(V | W), and it can be calculated using this formula
is an expression. And an expression is like an equation except that it has no "sides". Expression is something after being solved gives the answer. An equation on the other hand, shows something being equal to something else.
When adults with smartphones are randomly selected, 61% use them in meetings or classes, then
the probability of using the smartphone is
the probability of not using the smartphone is
If 8 adult smartphone users are randomly selected, the probability that exactly 3 of them use their smartphones in meetings or classes can be calculated using binomial distribution as
