A multiple choice exam has 10 choices for each question. A student has studied enough so that the probability he/she will know the answer to a question is 0.24, if he/she doesn't know the answer then the probability he/she will be able to eliminate one of the choices is 0.24, otherwise all 10 choices seem equally possible, and the student blindly guesses one out of all choices. If the student knows the answer he/she will get the question right, If not, they have to guess from the 9 or 10 choices depending on whether one choice is eliminated or not. What's the probability the students answer a question correctly? a. 0.3160 O b. 0.3187 c. 0.2667 O d. 0.2920 e. 0.4800

Suppose that you were challenged by a friend to hit the bull's eye of a circular board with two concentric circles namely the inner and the outer circles. Your probability of hitting a bull's eye from a distance is 0.05, the probability of hitting the outer circle is 0.75, and the probability of hitting the inner circle is 0.15. If you hit the bull's eye, he will give you 500 pesos. Hitting the inner circle will merit you 300 pesos and the outer circle, 100 pesos. How much is your expected winning? Select the correct response: 265 pesos none of these 95 pesos 145 pesos 335 pesos
