... • Let X = the number of questions Joan guesses correctly. • Then X takes on the values 0,1,2,3,4,5 • We can then find the probability for each of these values using our binomial formula. P(X=0) = 5C0 (.25)0 (1-.25) (5-0) = .2373 P(X=0) = 5C1 (.25)1 (1-.25) (5-1) = .3955 P(X=0) = 5C0 (.25)0 (1- ...

Chapter 13. What Are the Chances?
... Unconditional Probability – The probability of an event, which depends on no other event. The Multiplication Rule – Finds the chance that two events both happen. More specifically, the chance that two things will both happen equals the chance that the first will happen, multiplied by the chance that ...

Math SCO G1 and G2
... How do you calculate theoretical probability of tossing a 4 using a regular die? Determine how many times a particular outcome (possibility) exists in that situation. The number 4 is found once on the die. So the numerator needed for the theoretical probability is 1 since there is only 1 four ...
