Question

Player Jacob has a fair. 20-sided die with sides numbered 1 through 20 He rolls the die twice and wants to know the probability of the following outcomes occurring A: rolling a number less than 7 8: rolling a number that is a multiple of S In order to determine P(An B). Jacob completes the following steps. Use formula for probability of independent events. Step 1 P(AnB) P(A) P(B) Step 21 P(A)-" Step 3 | P(B)= - Determine P(A). Determine Multiply What mistake, if any, did Jacob make? O In Step 2,Jacob found the wrong value for P(A). As a result, Step 4 is also incorrect 0 In Step 1. Jacob identified the wrong f O In Step 4, Jacob multiplied incorrectly o in Step 1, Jacob used the wrong formula. o in Step 3. Jacob found the wrong value for P(B), As a result Step 4 formula. The events are dependent. As a result, step a is also incorrect used the wrong formula. independent events are found using P(AnB IA) PIBA) As a resuit. step 3 and step 4 are also incorrect. value for P(B). As a result, Step 4 is also incorrect. crect b did not make a mistake. His work and his a

Explanation / Answer

Here the events are dependent.not indipendent,

So we cannot use the formula for indipendent events here.

So both step 1 and hence 4 also wrong.

Option 2 is correct
