Question

3) Someone shoots 4 arrows at a target. These shots are independent of each other as events. The probabilities that they hit the target are given as follows: P -0,1, P-0,2, Pa-0.3, P-0,4 If three of them hit the target, compute the probability that they were the three first ones.

    Please give help for this question. Question 4. Coin tossing, again. In class on Monday, January 29th, we discussed an example showing that the conditional independence of events does not imply their unconditional independence. As a reminder, the setup of the example was as follows. We had two coins, coin A and coin B. We chose a coin at random (i.e., with probability 0.5) and tossed the chosen coin repeatedly. Given the choice of a coin, the coin tosses were...
