The conditional probability formula, P(A | B) = P(A ( B) / P(B), can be difficult to apply. First, mistakes can be made substituting the events in a problem for the generic A and B. Second, it is easy to forget that the probability that you divide by, P(B), must be the probability of the condition (the event after the bar) in the conditional ...

If we subtract out this double count, we have the correct probability: . P(A or B) The probability of either A or B occurring (or both) is. P(A or B) = P(A) + P(B) – P(A and B) Example 10. Suppose we draw one card from a standard deck. What is the probability that we get a Queen or a King?

The probability shaded greater than 0.905 is (1-0.8186) =0.1814. p-value = 0.1814. p-value is not less than alpha. So, we fail to reject Ho. 61. B The assumptions of the hypothesis test for a proportion are the data must be categorical, data must come from a random sample, np> 15 and n(1-p)> 15.

The opposite of at least one person having such a birthday is nobody having such a birthday. Below is the only branch of the tree diagram in which this happens. Once the probability of this path is found we subtract from 1. Answer is . 12. C) .8667 D) .9286. 13. B) P(no inf | successful) = P(no inf & successful) / P(successful) = .84/.86 = .9767

(Joint Probability Formula) For any two events A and B, P(A and B) = P(A) P(B| A). In English, “The probability that two things both occur (or ‘are true’) is the same as the probability that one of them occurs times the probability that the other occurs, given that the first did, indeed, occur.”
