A die is flipped two times. Letibe the random value of the first toss andjof the second LetX(i,j)=2i LetY(i,j)=i+j QUESTION>>>>>FindE(XY). Hint:PutZ=XY. You have to take all valuesZcan get and multiply them by the probability thatZassumes this value, and add it. For example, let sayz= 12. Fori=1,2i=2,soifj=5wehave2i(i+j)=2 Solution You can refer to this doc: http://www.stanford.edu/~henrya/math151/Hw8Sol.pdf.

A fair coin flipped 9 times. Use Appendix Table for Binomial distribution to find the probability that it lands on heads more than 5 times (5 is not included). Tip: first, figure out what is n, p, x for this case, then use Appendix Table to find each probability, then add them together. Solution n = 9 p = probablity of getting head = 1/2 x = 5 the probability that it lands on heads more than 5 times now we need P(x>5) P(x=6) + P(x=7) + P(x=8) + P(x=9) 9C6 (1/2)^6(1/2)^3 + 9c 7 (1/2)^7 (1/2)^2 + 9c8 (1/2)^8(1/2) + 9c9 (1/2)^9 = 0.25390625.

A dolphin moves in water towards an obstacle at a speed of 15 m/s. At 2m from the obstacle, it emits a signal whose speed in water is 1500 m/s. How much time does it take to receive the echo? If the response time of the dolphin is 0.1 s, can it avoid the obstacle? Solution Let t be the time at which the dolphin receives the return signal, and let d be the distance that the dolphin travels in that time. Then, d = t*15 m/s The original distance D from the dolphin to the object is 2 m. When the dolphin recieves the signal, he is at position D - d from the object. So the total distance traveled by the ultrasonic signal is: D + D - d = 2D - t*15 m/s = t * 1500 m/s 4 m = t*1485 m/s t = 2.69 ms At 2.69 ms, the dolphin has traveled d = 2.69 ms * 15 m/s = 0.04 m. So the object is 1.96 m away from the dolphin. At 2.69 ms + 100 ms = 102.69 ms, the dolphin has traveled d = 102.69 ms * 15 m/s = 1.54 m. So, having responded with 0.46 m to spare, the dolphin easily misses the object..
